iChewie Bop Top Airtight Container 16 oz, 4.13 in Cube with Pop-Top Lid

The lid shuts by a mechanical pop-top rather than a screw thread or a clamp: one press seals it, one press lets go.

Capacity is 16 fl oz, listed elsewhere as 500 ml, in a body 4.13 inches on every side with rounded corners. Those corners are why it rinses clean, since nothing wedges into a right angle.

Lid and silicone gasket both lift away completely, so the seal itself can be washed rather than harbouring old smells.

Squared sides let several sit one atop another without sliding, and the walls stay clear enough to read the contents through.

Shatter-resistant BPA-free ABS, rated for freezer use, weighing 0.19 kg. This size is one of a range reaching 135 oz.
