Your perfect strap-on experience is on lock with Doc Johnson’s deluxe line of full-service Vac-U-Lock Deluxe Sets.

The Vac-U-Lock Dual Density ULTRASKYN Set is a solid investment for upgrading or beginning your strap-on accessories collection, offering multiple options in one box via a complete harness with removable O-rings, a 7-function rechargeable vibrating Vac-U Plug with remote, three ULTRASKYN attachments, and a bottle of Mood water-based lube. These lifelike dual density attachments — an 8” Realistic Dong, a 7” Cock, and the bestselling 7” Slim Cock — warm to body temperature with use and feature a soft exterior that gives way to a firm inner core, recreating the feel of a real erect penis.

Attachments can be used with the harness, the included 360° Swivel Suction Cup, or any other accessory or harness in the line. The Vac-U-Lock Dual Density Starter Set also includes Doc Johnson Natural Toy Cleaner and ULTRASKYN Refresh Powder to properly and hygienically maintain your dual density ULTRASKYN attachments. Every product in the patented Vac-U-Lock system is designed to help you create any strap-on or toy you’re in the mood for, and it’s as simple as popping on the attachment of your choice.
