This is a vintage Apple "Hockey Puck" wired optical mouse.

The Apple Mouse, often referred to as the "Hockey Puck" mouse due to its shape, was introduced by Apple Computer in 2000 alongside the iMac G3. It was designed to complement the colorful, translucent aesthetic of the iMac and featured a unique, symmetrical, and spherical design that allowed for ambidextrous use. This design, however, proved controversial, with many users finding its lack of distinct left and right buttons and its smooth surface difficult to use precisely.
Despite its ergonomic criticisms, the Apple Mouse became an iconic piece of Apple's design history, representing a period of bold experimentation and distinct branding. It was eventually replaced by the more conventional, albeit still sleek, Apple Mighty Mouse in 2005. Today, these early Apple mice are sought after by collectors of vintage Apple hardware and enthusiasts of early 2000s technology.
