Since its arrival on ToyDemon, the SI-X series has become very popular due to its unique combination of simulation, durability, safety, and economy. ToysHeart took their "Fine Cross" material that was known for its durability and safety and made it into a foam structure for the SI-X. This made the material softer and more elastic without sacrificing "Fine Cross" original durability. This is Type S for the SI-X series. S is short for spiral and this sleeve has plenty of spiral for your pleasure. The interior is separated into three section of design. The beginning section called Quattro Spiral with four twisting ribs. Each Quattro Spiral Rib has four micro ribs running down its sides for more stimulation. The middle section is the Tre Spiral with three rounded, thinner rib wing twisting in an opposite rotation. The last twist area is called Magatama Spiral with its tight opening and a large twisting rib column. At the end of the sleeve is the large vacuum chamber lined with tiny nubs. Simply squeezing the air out as you enter to maximize the suction sensation of the SI-X Type S. To many, the best feature of the SI-X series is the price. SI-X offers such a great masturbator but is priced at one of the lowest for a reusable hand masturbator. This unique combination make SI-X a fan favorite and with amazing new design like Type S, SI-X is hard to beat.
