Self-imposed or a part of couple`s play, LOCKDOWN is a meaty-thick and weighty chastity toy. We made this one thicker--the rubbery soft silicone blend is stretchy but restrictive...an erection is difficult in LOCKDOWN. There`s more room inside: LOCKDOWN stretches to fit any size and the sling style base keeps it on. The ball-ring is more substantial, so it stays in place. More head room drives guys nuts. They get more sensation, more friction but can`t do anything about it. The curve in the shaft makes erections less comfortable, but keeps chastity possible under clothing with more bulge but still discrete. Gives a meaty bulge even if it locks down your cravings. Our plus+silicone TPR/silicone blend is Phthalate free. silicone for a smooth and warm feel and TPR for amazing stretch and strength. Dimensions: Width: 1.5 to 2 in. Height: 4.75 in. Depth: 1.5 in. Main Hole Circumference: 4 in. Shaft Hole Circumference: 3 in. Ball Hole Circumference: 3 in.
