FAQ
Is it microwave safe?
Yes, the main container and internal cups are safe for microwave use, provided the lids are removed first. This allows for warm lunches like pasta or rice to be served safely at school or nursery.
Can it hold liquids like soup?
It depends. While the silicone seals are highly effective for thick sauces or yoghurts, the box is not designed for thin liquids like soup. It is best suited for solid foods and thick dips.
Is the material safe for children?
Yes, the MB Tresor is manufactured from high-quality polypropylene and is entirely free from BPA and BPS. It meets all UK and EU food safety standards for peace of mind.

How to choose kitchen & dining
Choose kitchen equipment around the meals you make, the space you have and how you clean it. A durable item that fits your cooker and cupboard is usually more useful than a large accessory set.
| Check before buying | Why it matters | Trade-off or limit |
|---|---|---|
| Capacity, dimensions and compatibility | Check hob type, oven limits, cupboard clearance and portion size. | Large capacity can mean extra storage, weight and washing-up. |
| Care instructions and replacement parts | Look for replaceable seals, lids or handles and realistic cleaning requirements. | Dishwasher convenience may shorten the life of some finishes; follow the maker's instructions. |
| Materials and actual usage costs | Compare coating care, refill or filter costs and energy use where stated. | A premium material alone does not prove better cooking performance. |
Common mistake: Do not assume every stainless-steel pan is induction-compatible or every reusable container is freezer-, microwave- and oven-safe.
