Three Piece Dark Blue Crockery/Jar/Canister Set, Unbranded, Made in Italy

This is a nice set of crockery that I'll label as unbranded. There is a sticker on the bottom but I can not read it. There are no chips or cracks, although they could be cleaned up a bit. They look like they are terra cotta but I'm not sure. Measurements for the biggest and smallest ones are in the pictures.
