I love Iris tubs. Apparently they have some sort of coating on them that keeps them easy to remove dirt (and in this application, snake poo and urates). I would rate them at the top of the heap as far as plastic enclosures. Next would be the ones that come from the Container Store (completely clear instead of semi-clear but really sturdy). Then Rubbermaid (still great quality), Sterilite (don't love them. they crack easily and don't last) and last would be the kind you get from the dollar store. They should last 3-4 days

doll, if I'm not mistaken, www.reptiletubs.com sells the entire Iris line. I am sure somebody will clarify this. They don't sell them as Iris brand on the site but I believe they are either Iris or higher quality replications.
