what is the outer diameter of this sleeve?
Hello Pat. Each diameter will differ depending on the size.
is it tapered?
The hole that it goes into will need to be rounded and smoothed out. You don't need to do that to the insert.
Due to the time it takes to produce the VISE Ultimate Vinyl Oval Thumb Insert White ball it will ship in immediately. We cannot ship this ball outside the United States.
