KIIROO® Onyx+™ Replacement Sleeve - Single Pack

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.
