Dark pink side: Warms up strongly to 38°C Light pink side: Warms up gently to 30°C Body size: 32 x 21.5 x 1.4 cm I bought this for my pet and used it for one season, but my pet didn't like it, so I'm selling it. Operation confirmed. Instruction manual included. Cleaned with alcohol. When shipping, I plan to wrap the outer box with bubble wrap. Of course, it can be used for rabbits, and also as a floor heater to warm hamster cages. Please understand that this is a used item and has been stored at home before purchasing.
