Oppopet is a series of cutesy wireless mice coming from the joint efforts of Elecom and Nendo. The mouse is a 3-button optical mouse weighing 55 grams, works on 2.4GHz, and runs on a single AAA battery. The high point of the mouse is the USB receiver shaped like an animal tail, making it appear like a small, cutesy pet. Models released include fox, dog, dolphin, cat, pig, squirrel, chameleon, and rabbit.
