i don't know. they were the only plain white ones i could find at Lowes. i *HATE* shopping around (since i am a single man), i often run out of patience looking for the right thing and just buy whatever is at hand. i like simple, straight colors, without marbling (another thing i hate) or stone emulations. i just wanted a plain, straight, simple color, flat, and the only thing i found at lowes was this 2x2. but i appreciate your suggestion.
one of the worst things about doing home improv is having to go to different specialty stores. i am impatient and i want all in one, like lowes. not finding things at lowes and having to go to a plumbing or tiling store is a drag for me. i know, i am spoiled.
