the ones i looked at were plain glass, look by the floral section. i am going to do the cookie jar. i'm gonna make a bamboo fountain as a hood and for filtration. this should take me a while. when i get it done i will post it. i gotta set up my 40 gallon before i get into this. now to figure out a light source. dreaming it up is the fun part. i know the glass you are talking about. many hobby stores carry the same ones. rounded and cut at a slant or big square vases. i saw these at the hobby shop, before i saw them at lfs. same company selling 1 product for 2 different applications in 2 different places.
