Medium-sized Wacom pen tablet with buttons. Wacom Intuos Pro PTH-651 - Brand: Wacom - Connectivity: USB - Number of Buttons: 8 - Size: Medium Thank you for viewing. Power operation has been confirmed, but I'm not sure if the side buttons work. There is some stickiness on the pen due to aging. None of the replacement nibs in the stand have been used. I used it only once for an assignment, and then stored it in a dark place. No returns or exchanges, please.
