The Vac-U-Lock(TM) Dual Density Starter Set provides a fun and innovative introduction to strap-on sex with a complete harness with removable o-rings and plug, three moderately-sized ULTRASKYN(TM) attachments and a bottle of Mood water-based lube. These dual density attachments warm to body temperature with use and feature a soft, pliable exterior that gives way to a firm inner core, recreating the feel of a real erect penis. Begin your exploration with the pleasing ridges and plush balls of the 5.5 inch textured cock, or go a bit deeper with the 6 inch spiral dong. For the strongest and most lifelike sensation, choose the 7 inch thin dong's realistic proportions, contours, and vein details. Attachments can be used with the harness, the included Vac-U-Lock(TM) suction cup, and any other accessory or harness in the line. The Vac-U-Lock(TM) Dual Density Starter Set also includes Doc Johnson(R) Natural Toy Cleaner and ULTRASKYN(TM) Refresh Powder to properly and hygienically maintain your dual density ULTRASKYN(TM) attachments. Every product in the patented Vac-U-Lock(TM) 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.
