In 1991 a round crystal clear mouse was produced by Natico Originals. It is about an inch wider in diameter than the later iMac round mouse, even a little wider than the round DEC mouses of the late 1980s.
Its slim profile outclasses the klunky DEC shape, presaging the stylish iMac semi-transparent mouse of 1998. With its ice blue scroll wheel, light grey ball visible in the center, and black chips on a white motherboard it's a clean design. Two slim buttons flank the scroll wheel.
The mouse utilizes the PS/2 mouse port.
