This sleeve creates extra thickness and length for extra sensation during sex. Simply pull the flexible sleeve over the scrotum where it will remain solidly in place providing extra support. This extension sleeve easily adds an extra 3.8 cm to the length of your penis. The sleeve is made of firm, yet flexible material, which feels realistic. The firm glans ensures the perfect stimulation for your partner. Both the inside and outside feature a studded texture which ensures a perfect fit. Apply enough water-based lubricant to the penis beforehand and the sleeve is ready to use. The minimum opening for both penis and scrotum is 3.5 cm in diameter and stretches slightly.
