The ADJUSTfit 3-pack includes three additional inserts for more precise fit options—any size guy can feel our sheaths custom fit their size… add as many as you want, making the sheath feel like it is part of you, feeling firm from the base of your shaft to the tip of the sheath.

Adjustfit Inserts by Oxballs

OXBALLS makes the best cocksheaths: big ones, long ones, thick ones, and now skinny-thin sheaths… all designed to fit right and stay on. All our sheaths are built on our original cocksling base so they fit you no matter how hard you play. We include a bullet-shaped insert with every cocksheath to adjust the inside-shaft length for the best fit for you.

The clear rubbery inserts “disappear” inside the sheath for a discreet look… they keep the cocksheath firm even when you aren’t, so you can keep playing hard.
