How does a penis extender sleeve stay on? An extender is a hollow sleeve worn over the erect penis. The solid tip adds length, and the walls add girth. The weak point of any sleeve is slipping during thrusting. This Size Up extender deals with that using a ball loop: a ring at the base that goes around the testicles and anchors the sleeve to the body. With the loop in place, the sleeve moves with you instead of sliding forward.
Size Up 1 inch extender: realistic shape, secure fit
This Size Up extender is a flexible silicone sleeve worn over the penis. It adds 1 inch of extra length along with added girth. The outside is shaped like a real penis, with a thick, curved shaft and raised veins that give a partner more to feel during penetration. A ball loop at the base holds the sleeve in position.
Three stretchy rings are included in the box. The maker suggests using them for stamina. This is the flesh-toned 1 inch version. The sleeve is flexible, so it bends with the body during sex instead of feeling like a rigid shell.
Best for: For penis owners who want a modest increase in length and girth without a bulky sleeve. One inch is a sensible starting size for first-time extender users and their partners. The ball loop makes it a good choice for anyone who has had sleeves slip off.

How to use
Wash the extender and rings before first use. Put a small amount of water-based lubricant inside the sleeve and on the penis. When erect, slide the penis into the sleeve until the head reaches the end. Stretch the ball loop and bring it around behind the testicles so the sleeve sits snugly against the body. If you want to use one of the stretchy rings, put it on at the base. Lubricate the outside of the sleeve well before penetration. Start slowly so both partners can adjust to the extra size. Remove the loop and rings first when you finish.
Care
- Use water-based lubricant only, inside and out.
- Wash with warm water and mild soap, turning the sleeve inside out if possible to clean the interior.
- Let it air dry completely before storing.
- As general guidance, do not wear the ball loop or rings for longer than about 20 to 30 minutes at a time.
- Store it away from other silicone toys and out of direct sunlight.

Frequently asked questions
How much size does it add?
This version adds 1 inch of length, plus extra girth from the walls of the sleeve. The facts do not give the sleeve's total length or its diameter, so we do not list those figures.
Will it stay on during sex?
The ball loop is there for that. It goes around the testicles and anchors the sleeve at the base. Using only a little lubricant inside the sleeve also helps keep it from sliding.
What are the three rings for?
They are stretchy rings included with the extender. The maker suggests them for stamina. Remove any ring at once if you feel pain, numbness or coldness, and limit wear to about 20 to 30 minutes.
How is this different from the larger Size Up extenders?
The number in the name is the length the sleeve adds. This one adds 1 inch, the smallest step, which makes it the easiest to get used to. Larger versions are listed separately.
What lubricant should I use?
Water-based lubricant only. The sleeve is silicone, and silicone-based lubricants can break down the surface. Apply a little inside and plenty outside. Wash both sides of the sleeve after use.
