Ultracore Blue — CORE + AXIS Ball System by Oxballs

Ultracore Blue User Guide & Play Styles

Stepping up from a basic cock ring to the Ultracore Blue system

You’ve worn a cock ring before — now it’s time to feel what a purpose-built two-piece system actually does. Slip the blue CORE ballstretcher on first; the smooth inner tunnel delivers a medium-firm ball squeeze on its own. Then stack the AXIS power ring over the CORE’s outer ribs and feel the stimulation double. The interlocking rib channels grip and hold without slipping, so the sensation stays consistent whether you’re solo or mid-session with a partner. The extra-soft Plus Silicone body is body-safe and non-toxic, making cleanup simple — rinse with warm water and a toy cleaner after play.

Using the Ultracore Blue during couples play and shower sessions

The best cock ring for couples play is one that adds sensation for both partners, and the ultracore blue system is built with that in mind. The wave of squeeze from the stacked CORE + AXIS combo intensifies throughout a session, creating a tighter, more present feeling that both of you will notice. Because the silicone rings for men in this set are fully shower-friendly, take the fun into the wet room — the blue silicone grip holds even in water. Slip the AXIS power ring off first when you’re done, then ease the CORE free. Browse the full range at our Oxballs cock ring collection.
