Kuu-Sou Cube Ultra-Soft Onahole

Kuu-Sou Cube Ultra-Soft Onahole – Ultra-Soft Sleeve with Dense Cube Texture

The Kuu-Sou Cube Ultra-Soft Onahole expands the popular KUU-SOU collection with an innovative internal design and an exceptionally soft construction. Made from highly elastic ULTRASOFT material, this medium-sized sleeve offers remarkable flexibility and adapts smoothly to pressure while maintaining its shape throughout repeated use.

Its standout feature is the densely packed internal canal filled with large cube-shaped texture elements arranged from entrance to end. These evenly distributed structures create continuous multi-point contact across the entire canal, producing a varied tactile experience while preserving the soft feel of the material.

The dual-layer construction combines a supple outer surface with a resilient inner core, resulting in a comfortable balance of softness, elasticity, and durability. The closed-end design helps maintain the canal structure while enhancing the natural vacuum effect created during use.

The material has been developed to minimize odor compared to conventional sleeves, making maintenance more pleasant. Each unit includes a 5 ml lubricant sachet, allowing immediate use straight from the package.
