Thank you for viewing. Please be sure to read the product description and self-introduction. Marukan Hot Usa-Dan Yorisoi Heater ★ When fixed to the cage, this L-shaped heater warms like it's wrapping around! It warms from the sides and the bottom, making it perfect for senior rabbits. 【Specs】 * Material: ABS * Product Size: W355 x D230 x H30mm I purchased this about a year ago for a sugar glider, but because it was an acrylic cage, I couldn't set it up properly and it was stored unused. It's ultimately unused, but I opened the package, and there are no included instructions, etc. (I don't know if it wasn't originally included or if I threw it away) Box included Also, although it is an unused item, it has been in someone's possession once. Please refrain from purchasing if you are nervous about this. * Shipping will be a simple packaging method, wrapping the product box in bubble wrap and placing it in a bag. * Please consult via comments if you are in a hurry.
