Vac-U-Lock - Knuckle Up

Taking hands-on play to the next level, Doc Johnson's feisty Knuckle Up accessory will delight and amaze you with its novelty, functionality, and its undeniable "cool factor". Knuckle Up is compatible with the entire selection of Vac-U-Lock attachments, with its one-size-fits-all knuckle rings sitting below a standard Vac-U-Lock plug.

Taking the shape of classic brass knuckles, the firm ABS plastic grip fits through the fingers and provides a solid handle for ultra precise maneuvers once a compatible toy has been attached to the universal plug up top. Simply slide your penetrator of choice on, and enjoy.

You won’t believe how versatile this toy is. It’s perfect for both masturbation and for playing with a partner. Knuckle Up is ideal for anal play with its manageable size, and fits most hands.

Knuckle Up is easily cleaned with warm soapy water or your favorite toy cleaner, and is compatible with any chosen lubricant.
