KooK Glass Kitchen Canisters, Set of 2 with Airtight Lids and Chalkboard Labels, 6.1 inches Tall

Volume is the first thing to settle, because the listing cannot decide. Its product name says 29 oz, the size field says 32 oz, and two bullets claim half a gallon, which would be 64 oz. The measurements given, 4.7" square with rounded corners and 6.1" high, point to the lower end of that range.

Chalk is supplied alongside four interchangeable chalkboard labels, so a jar can be renamed when its contents change rather than carrying a permanent sticker.

Glass is described as chip-resistant, free of lead and free of cadmium, and the bodies are rated for machine washing and for the freezer. Two bullets repeat the same point in different words, which is worth knowing when reading the specification closely.

One bullet calls the material durable fiber glass while the material field says plain glass; fibreglass would be wrong for a food container, so read that phrase as a listing error rather than a specification. The pair weighs 1.57 kg.
