Well this is exciting. 

A bullet vibe with a textured surface, Je Joue’s Duet is a new way to play. The textured bumps allow for deeper penetration of vibrations, even when used externally.

What makes it a “Duet?” The textured surface is just one side of the toy. The other side is smooth, so you can play with sensation as you build up to orgasm. As with all Je Joue toys, this one’s got a deep, low rumble, for vibrations that hit more of your internal, pleasurable nerve endings.
