KIIROO® Onyx+™ Replacement Sleeve - Single Pack

The internal ridges catch just right on the thrust, that squeeze is no joke. I was worried a replacement wouldn't match the original fit, but this one slides on snug and holds up during use.

The fit is snug from the first push, and that internal ribbing really grips you on the way back out. Lasted through a few solid sessions before I swapped it for a fresh one, which is exactly what I needed.

The internal texture is exactly what I hoped for—definitely gives that snug squeeze during use. Fit is snug on the device and it feels like a fresh upgrade. Honestly, worth grabbing a spare so you’re never without it.
