To be fully enclosed is to be fully held — and there is a particular release in surrender to that. Enclosed is a weighted, precision-built form that opens flat and folds around you completely, creating an internal landscape designed to be felt deeply rather than quickly. A practice of presence, not a shortcut.

Two vibrating cores run the length of the firm-walled interior, whose rippling edges stimulate as you pass through and whose tighter squeeze holds you in for greater intensity. Five modes — low, high, pulse, alternating, and random — let the session evolve from slow arrival to full force at the press of a button, with side pressure pads for added control. The clamshell design opens completely flat for easy rinsing under lukewarm water and doubles as a drying stand, the slide arms holding it open to air out. At 530 grams and 68 by 80 by 175mm, with a 170mm insertion length, it has a reassuring, quality weight from the first hold.

A thermoplastic-elastomer interior sleeve sits within a polycarbonate shell with silicone and ABS components, waterproof to a shallow depth for rinsing though the charging base is not. It recharges over the included USB cable in about 90 minutes for roughly 40 minutes of use, and a sample of water-based lubricant is included. Store it clean, dry, and out of direct sunlight.
