They look great in person, the large and medium jars will be great for flour and sugar due to their size, the small not sure what I will use it for yet. The seal is nice and tight with rubber lining each lid. The only criticism I have is that the glazing is a little uneven on one of the jars. 

Pros: good sael, nice size, all look very uniform
Cons: small container seems out of proportion - a little too small for the set. Uneven glaze application
