Thank you for viewing. This is the Hot 2-Way Heater S from GEX. It's a floor heating system/heater for hamsters. I bought it for my hamster, but I couldn't figure out how to get the cord out of the cage, so I gave up. I opened it once to look inside, so I sealed it with tape. [See photo] I only opened the inner bag, but it's completely unused. I will ship it anonymously. Thank you.
