The tapered tip gives way to a 40mm body with a 128.8mm circumference, and that curve creates a full, anchored sensation that holds its position comfortably during extended wear.

The removable 80mm bullet slots inside and delivers vibration through the entire plug rather than concentrating it at a single point.  It offers seven speeds which give enough range to find what works, from a low steady pulse to something considerably more insistent. The power supply comes from a replaceable size N battery with around 2.5 hours of play time. The plug is made from body-safe silicone and ABS plastic, with an insertable length of 76.2mm and a total length of 135mm.

The Butt Throb is also fully waterproof to IPX7, with a wide, flat base which keeps the plug secure and makes removal straightforward. The bullet can also be removed for use on its own, which opens up a separate set of possibilities without taking up more space in the drawer.
