What do you call the tape that volleyball players used to their finger?

Answer 1

It's called athletic tape. You can purchase it from any drug store, Walmart, or sporting goods store. It's usually less than $5, and there are different widths. For fingers, we generally use 1.5" tape with some 3" for an anchor depending on the fingers that need to be taped and whether it is just for support or if it's protection from injury.

Pre-wrap is also recommended.
