"I use these bowls for all my desert type reptiles. I really like the way they look, and the plastic is easy to clean and its heat resistant! The bowls I keep stationary in one cage, while the food dishes I use for all my reptiles. Everything from live worms to yummy fruits; these are very useful. Come in varius earth tones like green, brown, grey and red. The small is about the size of your whole palm, so the other sizes are bigger than that. Agian, since the small is small, it holds very little liquid so I would use it for desert only, like a single leopard gecko. For bigger herps, like skinks for example, use the large. I'm not a fan of the price (yikes) but they are so useful and trust me, its worth it!!"
