Magnetic charging dock for a mouse. It can be used with mice that have a coin attached to the back, such as those from Logitech. I used it with a Logitech G Pro X Superlight, but it didn't fit my desk setup, so I stored it without using it much. The connector is USB-C. All accessories are included. As a bonus, I will also include a keycap puller for keyboards. Please use it for cleaning your keyboard, etc. I looked it up and it seems a new version of this product has been released, but it has flashy RGB LEDs, so this one might be better for those who want a calm desk environment. Instant purchase OK, please comment if you have any questions.
