I picked some of these up several years ago, and couldn't remember where I got them. I guess they are closing down because their factory in Japan shut down or something. Anyway, I thought I'd pass this along to you guys.

I painted mine the color of my apartment building and hung them at the front and rear doors. Then the HOA took the one off the front and threw it away with out any notice to me what so ever.
