Features: New and high quality Custom curved edge mouse skates. Mouse skates surface is flat and smooth after polishing, reducing the running-in period effectively, thereby extending smoothness and wear resistance. The round and full curved edge provides excellent fit, won't scratch the mouse pad, and improves upon the small size issue of previous versions. A wheel pressing process is added to prevent the mouse skates from denting internally. Provides smooth and quiet performance during use, with enhanced wear resistance on glass and resin pads. Equipped with 3M 468 adhesive for strong, durable bonding without delamination. Removable adhesive technology leaves no residue upon removal.
