Thread Reel is a device used to store and dispense thread. It consists of a SPOOL, which is a cylindrical object that holds the thread, and a reel, which is a wheel-like device that allows the thread to be pulled off the SPOOL. The term 'thread reel' is often used interchangeably with 'SPOOL, ' but it is important to note that the two are distinct objects. Thread reels are commonly used in sewing, knitting, and other crafts, as well as in industrial applications.
