Winproper Fruit Storage Containers, Five Sizes from 12 oz to 140 oz with Colanders

Sizes are published individually rather than as a range: 140 oz, 106 oz, 57 oz, 27 oz and 12 oz, adding to 10.15 litres across the five boxes.

Each box is double-walled with a colander that lifts out. Produce can be soaked, rinsed, drained and then stored without ever changing vessel.

Lids are best washed by hand. The maker warns that dishwasher heat may distort them, and asks that the cover be lifted away before anything goes in a microwave. Bodies handle both without trouble.

Four reinforced clips pull the lid down onto a silicone gasket, which is where the leakproof claim originates. The quoted working range is -20C to 120C.

Bases are raised, and the boxes stack as well as nest, so empty ones take less shelf than full ones. Polypropylene, free of BPA, 3.1 pounds for the set.

One specification line lists a built-in water filter. Nothing in the description supports it, and it appears to belong to another product.
