Double Play Vibe Set
 your player! Double Play lets you swap between a smooth bullet and a bumpy cupped vibe.
This mini vibe set gives you two interchangeable attachments to swap around depending on where the buzz is headed. There's a smooth bullet for roaming all over, plus a cupped stimulator with a bunch of nubby bumps inside for rubbing around outer sweet spots.
Take the bullet over clits, nipples, heads of penises, around your butt, or wherever else you want some direct vibration. Want more texture?
Pop it off and switch to the cup, then let all those little bumps join the fun.
The controller has a slider dial instead of a bunch of buttons to click through. Slide it one way for less buzz, keep going when you want more, or hang out anywhere in between. Much nicer when you know exactly how much vibration you're in the mood for.
Both attachments are smooth, nonporous plastic, so cleanup is quick and you can use them with any lube you like. Double Play runs on two AA batteries, sold separately.
