Oxballs Adjustfit Insert 3-Pack - Clear

This trio of clear inserts lets you dial in the exact fit of your favourite Oxballs cocksheath. Each soft flexTPR piece sits deep inside the shaft, shifting the internal length so the sheath hugs your body with more precision. The material is smooth, elastic and body safe, warming quickly against your skin and settling into place with a quiet confidence.

The inserts keep your sheath feeling firm even when you are not fully there, holding its shape so you can keep playing without worrying about slippage or collapse. Their transparent finish disappears inside the toy for a discreet, natural look. They are light, compact and easy to swap, which makes experimenting with comfort and sensation feel simple.

Ideal for anyone who wants their sheath to feel like an extension of themselves, these inserts support a secure, steady fit from the first stretch to the final press. Each one is made from washable, lube-safe flexTPR and can be used with water based, hybrid or silicone lubricants. Height is roughly 22 mm. Power is all you. No batteries. No fuss. Just a tailored, reassuring fit that moves with you. When you want a sheath that feels truly yours, these inserts help bring everything into alignment.

Enjoy the pleasure of a fit that feels considered, close and confidently under your control.
