Using your Kiiroo Onyx+ replacement sleeves is a breeze. First, make sure your Kiiroo Onyx (1, 2, or +) male masturbator is clean. Then, take one of the sleeves from the 3-pack and insert it into the masturbator. Use the Grip Clip to secure the sleeve firmly in place. You're now ready to enjoy the stimulating texture and the amazing pleasure it brings. When you're done, carefully remove the sleeve from the masturbator. To clean the sleeve, use mild soap and warm water. Gently wash the sleeve, making sure to clean all the textured areas. Rinse it thoroughly and let it dry completely before storing it. Keep the sleeves in a cool, dry place away from direct sunlight. Avoid using any harsh chemicals or abrasive materials on the sleeves, as this can damage the TPE material. With proper care, these sleeves will provide you with many more satisfying experiences.
