The Oxballs Cocksheath AdjustFit Inserts 3 Pack are replacement or additional sizing inserts designed to work with Oxballs cocksheaths. Each bullet-shaped insert shortens the internal shaft length by approximately 7/8 inches, letting you fine-tune fit based on your anatomy. Made from clear FlexTPR, the inserts sit discreetly inside the sheath and help maintain structure even when you're between full erections—useful for extended sessions or confidence during partnered play.
One insert comes standard with every Oxballs sheath; this 3-pack gives you the flexibility to stack multiples for a snugger, more customized feel. The inserts nest together inside the shaft, filling dead space and ensuring the sheath moves with you rather than shifting or bunching. They're particularly helpful for users on the shorter side of average or anyone who finds off-the-shelf sheaths too roomy at the tip.
Worth noting: these are accessory inserts only—you'll need an Oxballs cocksheath separately. The inserts don't change external girth or length; they adjust internal fit so the sheath feels like an extension of your body rather than a loose sleeve.

How to Use
Insert one or more bullets into the tip of your Oxballs cocksheath before putting it on. Start with one insert and add more as needed to eliminate excess space at the tip. The inserts nest together and stay in place once the sheath is on. After use, remove the inserts, wash both the sheath and inserts separately in warm soapy water, and air dry before storing.

Frequently Asked Questions
Do the AdjustFit inserts work with all Oxballs cocksheaths? Yes—they're designed to fit any Oxballs cocksheath built on the cocksling base. They may not fit sheaths from other brands due to size differences.
How many inserts should I use? Start with one and add more if needed. Each insert shortens the internal shaft by about 7/8 inches, so stacking 2-3 can reduce length by up to 2.5 inches total.
Are the inserts noticeable during use? No—the clear FlexTPR material blends into the sheath and feels like part of the shaft. They're firm enough to provide structure but soft enough to move naturally.
Can I use the inserts without a cocksheath? No—these are accessory inserts only. They're designed to sit inside an Oxballs cocksheath and won't function on their own.
Do the Oxballs AdjustFit Inserts ship discreetly to Canada? Yes—every order ships in plain, unmarked packaging with confidential billing.
