Logitech MX ERGO (MXTB1d) Advanced Wireless Trackball This is a trackball mouse from Logitech. I used it for about 3 days after purchasing it new, but it was too big and didn't fit my hand, so I've been storing it at home. Operation confirmed. All accessories are included. The box is torn. I think the main body is in good condition without any stains, but please purchase it after acknowledging that it is a home-stored item (I don't smoke, and I don't have pets or children). We will ship it immediately with a tracking number. *No comments are needed. Immediate purchase is OK. Please understand that we are not considering price reductions.* Logitech Wireless Trackball Mouse MX ERGO Ergo MXTB1d Bluetooth Unifying Wireless 8 buttons Rechargeable Fast charging Windows Mac iPad OS Chrome Domestic genuine product
