Unleash the power of the deep with the Spiral Valve Hard, a premium collaboration between Magic Eyes and famed designer Cyber Iguana. Inspired by the valve-shaped intestines of a shark, this unique masturbator recreates the sensation of being tightly “wrung out” by seven spiraling ridges that twist around your shaft with incredible pressure.

This hard version delivers a denser, more intense squeeze than the soft model — perfect for users who crave firm resistance and high stimulation. The non-through design creates strong vacuum suction, while the spiral structure compresses and releases rhythmically as you thrust or twist the toy, mimicking a living, gripping sensation.

The exterior features realistic folds and a hooded entrance inspired by the “shark girl” concept, making each session as visually exciting as it is physically thrilling. Beautifully presented with box art by Okuva and a bonus postcard illustrated by Mick, this 900g masterpiece is made to satisfy both collectors and pleasure-seekers alike.
