The interchangeable sleeve featuring the heroine Alya is the perfect way to take sensations to the next level and dive even deeper into the magical forest world of this sensual warrior. The sleeve is made from soft, body-safe TPE material that faithfully reproduces realistic tactile sensations for comfort and intensity with every session. The carefully designed Alya-inspired internal textures offer a stimulating variety of stimuli, so each use brings a fresh and exciting sensation. Replacing the sleeve not only allows you to add variety to the experience, but also to keep the device in excellent condition and prolong its life.
