It's clear, you won't find anything better for preserving your food. These 2 trays are perfectly airtight and have a very soft (and strong) film in the centre so they adapt perfectly to the shape of the food to be preserved and act like a vacuum. No more need for clingfilm or foil, just place the foodstuffs you wish to keep in the trays and stack them in the refrigerator to save space! Of course they can be reused as often as you wish! Dishwasher proof. Plastic. Dim. 30.5 × 23 × 3 cm approx.
