Product details

Core Definition

Swell Lock is an inflatable canine shaft: 17.4 cm overall, 14.2 cm insertable, with a hollow knot that expands from 5.0 cm to 10.0 cm across through a valve at the base. Shore A10 platinum-cured silicone over a hollow core.

How It Works

Static lock. Deflated, the knot is 5.0 cm across and passes as a single step: pressure builds, the sphincter has to release, then the knot drops in. Behind it the body narrows into a collar, the sphincter closes onto that collar, and the shaft is held in place without muscular effort.

Inflation. A magnetically coupled valve sits on the side of the base and takes a hand pump. Pumping expands the knot in place, from 5.0 cm up to a 10.0 cm limit, and it can be stopped and held at any point between the two, so girth is set during use rather than chosen at checkout.

Release before withdrawal. An inflated knot cannot pass back through the sphincter, which is the point of the design and also its limit: open the valve and let the knot return to 5.0 cm before pulling out, every time. The head and base stay solid, so only the shaft and knot change volume.

Who It's For

The 5.0 cm static knot is the entry requirement, so this assumes prior knotting experience and existing stretch training. Beyond that it suits users who want girth they can change mid-session and hold. Not for beginners, not for anyone new to inflatable toys, and not for anyone unwilling to deflate before withdrawal — a knot left inflated will not come back out.

Care & Safety

Molded from 100% platinum-cured silicone: non-porous, phthalate-free and heat-stable. Wash with warm water and mild soap, or a dedicated toy cleaner, before and after every use; boil for two to three minutes for full sanitization. Use water-based lubricant only, as silicone lubricant attacks the surface. Dry completely, then store flat and away from other silicone items. Stop use if you feel pain, use a barrier when sharing, and keep away from anyone under 18.
