When you want more stretch and comfort in a wearable ring, consider the Momo. As throbby as the Black Swallowtail, but the material is much stretchier ring design and the single ring is a simpler design. Easily worn on a penis, dildo, or held snug onto some fingers, the Momo puts it right where you want it.
Not waterproof, so be careful not to get secretions or water in the recharge port, but it's super easy to take the vibrator out and just wash the holder.
