Sanko Jungle Gym Arch for Land Hermit Crabs This is a jungle gym that encourages hermit crabs to exercise. I bought it intending to keep hermit crabs, but I haven't been able to get any, so I'm selling it. I haven't used it because I don't have any hermit crabs, but it seems to have rusted in one place during storage. Please check the photos. Since this is made of wire, I will ship it via Yu-Packet Post (Japan Post's service) and will flatten it slightly to fit in the post. Thank you for your understanding.
