These inserts are made to match your radius platten or diameter of your wheel. This is just the insert and not the stick that is needed to hold the insert. If you need a insert with the stick please go here Sanding Buddy – Silver.
Custom sizes take approximately 1 week for model creation and print time. You should get an email from Kyle@KHDailyKnives.com asking what your custom size is shortly after your order is placed.
