This is a heating mat for small animals made by GEX. I have been using it for about a year. Please refrain from purchasing this item if you are sensitive to used goods. Operation has been confirmed. It has been lightly cleaned. Shipping will be done via Yu-Yu Mercari Mail, which is anonymous shipping. If it's convenient, I will ship it within 24 hours. It will be wrapped in bubble wrap and then placed in a plastic bag before shipping.
