A vibrating butt plug adds internal stimulation and a satisfying sense of fullness, and this one delivers 10 vibration modes across 5 speeds & 5 patterns. The gently tapered tip eases insertion, making it a comfortable pick whether you are new to anal play or an experienced explorer. It is made from durable, body-safe PVC and is 100% phthalate-free. It measures 4.75 inches in length with a 3.25 inch insertable length, 1.25 inches wide with a 3.9 inch girth, and a 2.35 inch wide base. With an IPX7 waterproof rating, it is fully submersible. It charges over USB with the included cable, so there are no batteries to replace.
