I know a lot of people on here, myself included, like the look of the RBI hides.
At the chinese restaurant i usually go to they use these containers, sometimes in white, sometimes in black.

All you have to do is cut an entryway in them and melt the edges a bit and they're almost exactly the same as the RBI hides. There is more grooving on them, so cleaning them is a bit more work, but they sell on amazon for under a dollar a piece. My cinny is about 300g's now and she still fits under it just fine. I'd say they're good for balls up to about 500g's, idk for sure though. I've been saving them and using them for a little while now but don't eat that much chinese food. They've worked great for me, just thought i'd share in case anyone else wanted easy, cheap hides.
