KISS-X is made for the trans-masc person not in medical transition or who may be early on in their HRT. The new snugger version also has a different shape at the base. The KISS-X is a purposefully designed suction stroker to fit over the clitoris, while maintaining the style and benefits of the Buck-Off.
Made of SilaSkin (a TPR/Silicone blend formula) that's been raved about and is used in many of the Buck OFF products. The uber soft and sensual material makes the KISS-X pliable and pleasant to the touch.
