The softer and more elastic feel of SI-X masturbators were achieved using the "Fine Cross" material without sacrificing durability. Type R is the intense version of the SI-X in terms of its sensation. The inner wall is packed with ribs and nubs to give you a great sensation while still providing a tight feeling. The entrance is also made to retain lubricant for long lasting enjoyment.
*Use only water-based lotion or lube with this product.
