Howard Elliott Glazed Ceramic Flower Or Decorative Home Vase Set, Cobalt Blue, 2 Piece, 7 x 12 Inch and 5 x 9 inch

I ordered these vases, my larger vase is considerably lighter than the shorter vase....anyone else experience this? Thought they'd match.

Are these vases packaged properly to avoid breaking? Want to order but will have to travel a long way

Are these flat or round?
