Founded in Osaka, Japan, CatEye is the world's leading manufacturer of cycle computers, lights, and reflectors. In 1964, CatEye created the first flashing lamp for bicycles. It went on to create the very first bicycle headlamp using white LEDs in 2001. The company is truly a world leader in lens and reflector technology. Thus it is no great surprise that they have created this waterproof capsule just perfect for carrying your tools on your bike. There are two sizes to choose from as indicated in the pictures.
