Harnesses & Dildos by Doc Johnson

Vac-U-Lock is a patented dildo system that uses a special graduated plug that inserts into a shaft and then fits onto a harness or other Vac-U-Lock accessory. Vac-U-Lock products can work with other harnesses if they have a flared base or you have the plug accessory to give it a flared base. If you have questions on compatibility issues, feel free to contact us.
Never use oils with Vac-U-Lock products.

Vac-U-Lock products require using powder to get them on and off easily. Vac-U-Lock sells powder but it is talc, which is not a healthy option as it has been suggested that talcum powder might cause cancer in the ovaries. Therefore, we recommend using Cyberskin powder instead.
