Open tunnel plug silicone size S 7.5 cm — Extreme Hollow

An open, bell-shaped tunnel—no knots, no bulges, just a round opening at the top that keeps the canal gaping. The S from Addicted Toys' Extreme Hollow line is an introduction to the tunnel concept: the sphincter closes around the narrow neck under the plug's body, and the inside remains accessible.

The tunnel sensation without force

Upon insertion, the flared profile guides the sphincter over a progressively widening diameter towards the base—no abrupt step, no pop. The inverted bell shape settles once the neck is passed, and the inner tunnel remains open. This format allows you to feel the air, explore with a finger, or simply wear the plug while enjoying constant, gentle dilation. 140g of matte charcoal gray silicone, flexible and smooth to the touch.

The first in the Extreme range

The Extreme Hollow range is available in S, M, and XXL. The S is the right entry point: wide enough for the tunnel effect to be felt, compact enough to remain comfortable for a long period. The wide flat base ensures stability—no risk of migration. If you're already familiar with the knotted hollow tunnels from the same brand, the concept here is different: the expansion is continuous and uniform, not in stages.
