GOCAPA
Iconic Knot Structure and Sculpted Girth Inheriting the bold aesthetic and iconic knot design of our famous Graemen fantasy dildo, Gocapa is a premium wearable sheath engineered to increase girth, structural presence, and internal fullness. Featuring raised vein detailing and a prominent knot, Gocapa delivers unforgettable sensory feedback with every thrust.
Key Features & Design Highlights
- Graemen Knot Structure: Features a distinct, swollen knot bulge near the rear shaft, providing a satisfying threshold-stretching sensation upon deep entry.
- Sculpted Veins & Smooth Interior: Bold, raised outer veins maximize surface friction for your partner, while the silky-smooth inner wall ensures low-friction, seamless comfort against your skin.
- Balanced Single-Firmness Density: Specially formulated density provides enough column rigidity for easy insertion while retaining high stretch elasticity to adapt comfortable to your natural length.
- Integrated Base Ball Loop: Designed with an ergonomic hole at the base to anchor around the testicles, securing the sleeve firmly in place to prevent slipping during movement.
- 100% Body-Safe Platinum Silicone: Crafted from high-grade platinum-cured silicone—odorless, non-porous, hypoallergenic, and fully boilable for thorough sterilization.
How to Wear & Use
- Apply a generous amount of water-based lubricant inside the sleeve and on your shaft.
- Carefully slip the sleeve over your member.
- Gently guide your testicles through the opening at the base to lock the sheath securely in place.
