This Kraken dildo is made of sturdy, super-smooth borosilicate glass. This type of glass, commonly found in kitchenware, is not only durable and high-quality, but it can also withstand temperature changes, allowing you to warm it up or cool it down before insertion! The tip tapers to facilitate insertion, gradually widening towards the base. Along the shaft are spirals of octopus tentacles with small suction cups that add texture to the shaft and stimulate you during each playful session. The base flares out so you can combine it with a strapon harness, as long as the O-rings are soft. Be sure to use soft O-rings on the sturdy glass, such as silicone or rubber, and never use it with metal O-rings! This glass dildo is phthalate-free and safe to use with any type of lubricant. To clean, use lukewarm water and a toy cleaner. It is dishwasher safe, but exposure to boiling water may result in color fading.
