Translucent blend of silicone and TPR that results in a very soft, flexible penis extension that ads girth and length. This unique design gives a bit more headroom inside for him, so there is a little room to move around at the tip and soft nubs inside the tip give him stimulation. For her the outer shaft is very smooth until you get about halfway down where the girth increases and nubs for her begins. Phthalate free and body safe. Use with water based personal lube for maximum stimulation and comfort.
