Sanwa Supply Wireless Blue LED Mouse (5 buttons, Black) MA-WB509BK

This is a 5-button wireless mouse with convenient [forward] and [back] buttons for internet browsing. It has a standard size and a comfortable, fatigue-reducing shape. It's a wireless type that can be used without worrying about cables. It uses the 2.4GHz digital band, which is resistant to radio interference, and provides stable data communication over a wide range of up to a radius of 10m. The receiver is extremely small at 14.2 x 18.5mm, so it doesn't protrude much when plugged into a port, and it won't get in the way when carrying or storing your laptop with the receiver plugged in.
