The Vacuum Injection Method

For the most realistic and immersive experience, the makers of Onatsuyu recommend a specific application technique: Squeeze your onahole tightly to expel the air from the internal canal, then hold the precision nozzle against the opening. As you gradually release your grip, the sleeve will "inhale" the lubricant deep into its textures. Finish by gently massaging the unit to ensure a perfect, frictionless coating from entry to end.

Usage & Care

Clean your items thoroughly after use with lukewarm water and mild soap. Onatsuyu is formulated to be low-residue and easy to rinse. To maintain the "mint condition" of your collection, apply TPE Renewal Powder once your items are dry. Only use with water-based products.
