Tefal Masterseal Rectangular Plastic Container 3.7L K3022012

Our review

This is a rectangular plastic food storage container from Tefal's MasterSeal Fresh Box range, sized at 3.7 litres and listed under model K3022012. Its distinguishing point is the lid: instead of a separate seal that can shift or leave gaps, the freshness seal is built into the lid itself. That matters most for anyone packing salads, cut fruit or leftovers and finding them limp or leaking by lunchtime. The rectangular shape generally stacks and uses fridge space more efficiently than round tubs. Before buying, think about whether 3.7 litres suits your portions and whether the footprint fits your fridge shelf, bag or cupboard. Compare with clip-lock glass containers if you want oven or microwave reheating without staining, and with basic snap-lid plastic tubs if weight and cost matter more than seal reliability. Check the lid closure and care instructions on the listing, since none are given here. Available on Sokonia.
