Aizam Japan Concentrated pure crystal

Aizam Japan Concentrated Pure Crystal is a transparent non-penetrating masturbator that lets you see the interior mechanics during use. The construction uses a clear material that remains optically transparent, so the internal structure — and the visual of the stroke — is visible from the outside. The material is compliant with Japan's Food Sanitation Law Standard No. 370, indicating food-grade safety standards applied to the compound used.

Internally, the design features a cross-shaped channel structure that is mist-textured and twisted 90 degrees at the midpoint, creating a spiral effect as depth increases. At the deepest section, the channel narrows into an ultra-tight vacuum space described as a pseudo-uterine structure. The closed end traps air and creates suction during withdrawal. The combined effect of the spiral channel twist and the deep vacuum space gives this toy a two-stage stimulation profile: spiral friction during mid-stroke, intense suction pressure at full depth. Lotion is included. Produced in Japan; ships DDP from our Tokyo warehouse — listed price includes customs duties and international delivery.
