We just need to make sure you’re not a robot. A volleyball is a ball used to play indoor volleyball, or other less tachikara volleyball ball variations of the sport.
Volleyballs are round and traditionally consist of eighteen nearly rectangular panels of synthetic or genuine leather — arranged in six identical sections of three panels each, wrapped around a bladder. Indoor volleyballs are designed for the indoor version of the sport, the FIVB adopted as its official indoor ball a new Mikasa with dimples and only eight panels for a softer touch and truer flight. A valve permits the internal air pressure to be adjusted.
Beach volleyballs are slightly larger than standard indoor balls, and beach volleyballs for the beach game. Indoor volleyballs may be solid white or a combination of two or three different easily distinguishable colors.
