Did we say Heated Mice Houses? The “Claw” Palotix USB Heated Mouse Pad/Hand Warmer is said to keep your hands warm and cozy, as it heats up to 113 degrees. There's an integrated wrist pad for comfort and support. The heating element uses computer USB Power, or a 5V phone charger or even a portable power bank. As of 11/13/20, you could get it for under $10 by using a 'click for $8 off' button.
The VVS-eLife grey heated mouse garage looks like a sad face or something like that. If you feel that high heat is too hot, set the switch to medium (green) or low (blue). You can also set the auto time off. The default is 2 hours. You can also set it for 4 or 8 hours. It was about $20 on 11/13/20.
