Specialty Gardening: Has anyone seen these?, 1 by ardesia

I like to raise my outdoor plants up off my deck; it protects the wood and helps with drainage. About 5 years ago I found these little stands for $1 each at Big Lots but I have never seen them again. The ones I have are about 6" in diamer and just 1" high. I have lots of "pot feet" for the same purpose but I like these better. They have held up well but I need a dozen or so more and I can't find them anywhere.

If you have seen these or something close to them I would love to hear about it.
