FAQ
What's the size difference between the Sistema KLIP IT box and the MCIRCO glass containers?
The Sistema KLIP IT Food Box is a generous 9.6 litres, ideal for storing larger quantities of leftovers or bulk ingredients like potatoes. The MCIRCO glass containers come in various sizes – typically ranging from 0.5L to 1.8L – offering more flexibility for smaller portions and individual items.
Are both sets suitable for long-term freezer storage?
Both options can be used in the freezer, but the Sistema KLIP IT is designed with thicker plastic that's better suited for prolonged freezing periods (up to 3 months) compared to the glass containers which could risk cracking from significant temperature changes.
How do the prices compare between these two sets?
Generally, the Sistema KLIP IT Food Box tends to be priced slightly higher, often around £25-£35 depending on retailer offers. The MCIRCO glass containers are typically available for £15-£25 for a 10-pack, making them a more budget-friendly option.
What materials are the containers made from?
The Sistema KLIP IT box is manufactured using BPA-free polypropylene plastic, known for its durability and resistance to warping. The MCIRCO glass containers are constructed with borosilicate glass, which is renowned for its heat resistance and ability to withstand dishwasher cycles.
How easy are they to clean?
Both sets are dishwasher safe, though hand washing is recommended for the glass containers to prolong the lifespan of the locking lids. The Sistema KLIP IT’s airtight seal may require a little extra rinsing after cleaning.
Are there any safety regulations or certifications I should be aware of?
Both products comply with European food contact material regulations, ensuring they are safe for storing food. Always check the manufacturer's website for specific product certification details.
Could I use these in the microwave?
The Sistema KLIP IT box is microwave-safe but avoid prolonged high-heat microwaving as this can potentially damage the plastic. The MCIRCO glass containers are also suitable for short bursts in the microwave – check manufacturer guidelines.
Are they stackable, and how well do they nest?
The Sistema KLIP IT is specifically designed to stack efficiently thanks to its interlocking clips, minimizing wasted space. The MCIRCO glass containers can be stacked, but aren’t as tightly nested due to their shape.
What's the best way to maintain the airtight seals?
Regularly clean the lids of both sets with a damp cloth and ensure they are completely dry before closing. For the Sistema KLIP IT, occasional lubrication with food-grade silicone grease can help maintain the seal.
Are these suitable for storing seasonal produce like pumpkins in autumn?
The Sistema KLIP IT's large capacity makes it a good choice for bulk storage of root vegetables and other seasonal items. The MCIRCO glass containers are also suitable, particularly for smaller quantities and herbs – consider using them for preserving smaller batches of chutneys or jams.
In depth
Choosing kitchen storage is often deceptively complex; it’s not simply about finding containers that hold food – it's about selecting solutions suited to the realities of British kitchens and lifestyles. Our comparative analysis here focuses on two popular contenders: the Sistema KLIP IT Food Storage Box and the MCIRCO Glass Containers. We approach this selection with a layered methodology, starting with fundamental material properties like durability and chemical resistance, then moving onto practical considerations such as stackability, ease of cleaning, and suitability for specific UK culinary habits. Crucially, we’ve assessed each product against typical storage conditions within a UK home – the generally cooler temperatures found in most kitchens, the potential for frost buildup in freezers (a significant factor given the damp climate), and the varying sizes of homes across the country, from compact flats to sprawling detached houses. Ultimately, our goal is to provide shoppers with clear guidance on which container type best aligns with their individual needs and budget, informed by a deep understanding of what makes for effective kitchen storage in Britain.
The Sistema KLIP IT range has built its reputation on robust construction and an ingenious locking system designed for stability – a key feature considering the UK’s propensity for hurried meal prep and potentially chaotic fridge layouts. The plastic construction is inherently lightweight, which is advantageous in smaller kitchens or when moving containers around, but also means it's susceptible to cracking if subjected to extreme temperature fluctuations or significant impact. We’ve found that while Sistema excels at maintaining airtight seals, particularly against common kitchen humidity, the plastic can absorb odours over time, especially with strongly flavoured foods like cheeses and herbs. A significant selling point for Sistema is its stackability; the KLIP IT boxes are designed to nest neatly within each other, maximising storage space – a vital consideration in UK homes where floor space is often at a premium. The price point sits firmly in the mid-range category, typically around £25 - £40 per set of several boxes, reflecting the brand’s established market position and the quality of its engineering.
Conversely, the MCIRCO glass containers represent a shift towards more traditional materials. Glass offers superior resistance to staining and odour absorption compared to plastic, making them ideal for storing delicate ingredients like sauces or fresh produce. The locking lids on these containers are generally considered very secure, though some users have reported that the silicone seals can degrade over time with repeated microwave use – a common concern given the prevalence of reheating meals in UK households. Glass is heavier than plastic, which could be an issue for those with limited storage space or mobility issues; however, this weight also contributes to the containers’ perceived durability and resistance to warping. The price of the MCIRCO set is generally lower, hovering around £15 - £25 for a 10-pack, positioning them as a more budget-friendly alternative. It's worth noting that glass containers aren’t ideal for prolonged freezer storage; while they *can* be used, expansion and contraction due to temperature changes can put considerable stress on the lids.
A recurring issue among UK consumers in this category is a misunderstanding of ‘airtight’. While both systems advertise airtight seals, the effectiveness varies greatly depending on usage and environmental conditions. In a consistently humid UK kitchen, moisture ingress will inevitably occur to some degree, potentially affecting the shelf life of stored food. It’s crucial to understand that no container is truly 100% waterproof; even the best seals can be compromised by prolonged exposure to water or extreme temperatures. Furthermore, many buyers overlook the importance of proper lid closure – a loose lid significantly reduces the effectiveness of any airtight seal. We've observed a tendency amongst some consumers to overestimate the capacity of these containers, leading to overcrowding and compromising the integrity of the seals themselves.
Another prevalent mistake is failing to consider the specific needs of the freezer. While both sets are technically freezer-safe, plastic containers can become brittle at low temperatures, increasing the risk of cracking. Glass containers, as mentioned earlier, require careful management regarding temperature fluctuations to avoid lid failure. The UK climate presents a particular challenge; frequent periods of frost and thaw can accelerate material degradation, shortening the lifespan of even the most robust storage solutions. Investing in a good quality freezer mat – often overlooked by budget-conscious buyers – can mitigate some of these issues by providing an extra layer of insulation and protecting containers from direct contact with cold surfaces.
Finally, it’s important to acknowledge the varying demands placed on kitchen storage within different UK household types. A small flat in London might prioritize compact, stackable solutions like the Sistema KLIP IT, while a family home in the Cotswolds could benefit from the durability and robust sealing of the MCIRCO glass containers – particularly if they regularly freeze larger quantities of food. Regulatory considerations are minimal in this product category; however, BPA-free certifications for plastic containers and food-grade safety standards for glass are important factors to consider, especially when storing baby food or preparing meals for vulnerable individuals. Ultimately, selecting the ‘better’ kitchen storage solution depends entirely on individual priorities and usage patterns, underpinned by a realistic assessment of the challenges presented by the UK climate and home environment.
