What is a Signature Stroker? Signature Strokers are Doc Johnson's line of masturbation sleeves cast from adult performers. Each one is molded directly from the performer's body, so the outside reproduces her real anatomy, and each is made in ULTRASKYN, the maker's soft TPE material. The inside is a textured channel designed for stroking. They are simple, manual toys: there is no motor and nothing to charge. You add lubricant, slide in and control the speed and grip with your own hand.
Signature Strokers Lulu Chu: molded from the performer
This Signature Stroker is molded directly from adult performer Lulu Chu and handcrafted in ULTRASKYN, Doc Johnson's lifelike TPE. The interior is tight and textured, and the material warms to the touch, which adds to the realistic feel. It is a plain manual sleeve with no case or mechanism listed, so the grip of your hand sets the pressure. The material is phthalate-free.
Best for: For fans of Lulu Chu and for men who want a realistic sleeve without extra hardware. A soft sleeve like this is light and easy to use. It suits solo use and can also be handled by a partner during foreplay.

How to use
Rinse the stroker with warm water before first use. Put a good amount of water-based lubricant into the opening and on yourself. Enter slowly, since the channel is tight, and add more lubricant if you feel any drag. Hold the sleeve in one hand and stroke at your own pace. Squeeze harder for a tighter feel or relax your grip for a lighter one. When you finish, flush the inside with warm water and mild soap, shake out the water and leave the sleeve to air-dry.
Care
- Use only water-based lubricant with TPE.
- Wash inside and out with warm water and mild soap after every use.
- Let it air-dry fully; trapped moisture shortens the life of the sleeve.
- Store it on its own, away from other toys, heat and sunlight.
- Never boil it or put it in a dishwasher.

Frequently asked questions
How tight is it?
The maker describes the interior as tight and textured but gives no measurements for the channel. ULTRASKYN is a stretchy TPE, so the sleeve gives as you enter. Use plenty of water-based lubricant for comfort.
Does it come with a case?
No case is listed in the product information for this model. If you want a Lulu Chu stroker in a hard shell with variable pressure and storage caps, look at the Main Squeeze Lulu Chu instead.
What lubricant should I use?
Water-based lubricant only. The sleeve is TPE, and oil-based or silicone lubricants can break the material down. Wash the lubricant out with warm water and mild soap afterwards. Reapply as needed.
What size is the stroker?
The product information lists only the retail package size, not the length or width of the sleeve itself, so no dimensions are given here. Check the listing photos for a sense of scale.
