AdjustFit Insert 3-Pack Clear — Custom Fit CockSheath Inserts by Oxballs

Get the perfect fit every time with the AdjustFit Insert 3-Pack Clear from Oxballs. Designed to fine-tune your sheath’s internal length, these bullet-shaped FLEXtpr™ inserts reduce the inside shaft by about 7/8” each, giving you the power to stack, mix, and match until your sheath feels like a natural extension of you.

Discreetly clear and rubbery, AdjustFits “disappear” inside the sheath while keeping it firm—even when you’re not at full hardness—so you can keep playing longer, harder, and with total confidence.
