Contents: [Unused] 2 Hamster Sand Bath Heaters [Unused] Sand Bath Sand [Bonus] Used Sand I'm selling the sand bath heaters because I bought them without checking the installation points and they don't fit my cage. (Recommended for hamsters in wire cages) Put in play sand for a sand bath! You can also remove the sand bath and use the panel heater underneath on its own! *Please check the installation points before purchasing. *I opened the box once, but I haven't opened the contents. They are unused.
