Already know your size? This kit helps you find your length!
If you have around 50% coverage or more, you might want to look into a longer P-tainer. The extra length gives your skin more room to roll up onto the body of the P-tainer. This kit sends ten Demo P-tainers in the size you pick, from +5mm to +50mm in 5mm steps, so you can try each one and see which length works for you.
It works for intact guys too, although with full coverage you may need something longer than the +50mm in this kit. If that’s you, a single Demo P-tainer comes in lengths all the way up to +75mm, so you can try just the longer sizes you need.

Wear each one before buying the real thing
Size and length marked on every knob

Designed and manufactured in Texas
The length number is how much longer the body of the P-tainer is than our standard +0mm. Start at the short end and work your way up until one feels right.
The Demo P-tainers in this kit are the same size and shape as our normal P-tainers, but with a few differences:
Once you know the exact size and length that works best for you, a Dishwasher Safe P-tainer is our recommended plastic device for day to day wear: smooth matte finish, high temperature resistant, and 100% solid for maximum heft. Most people eventually upgrade to the Stainless Steel P-tainer to take advantage of its built-in weight, unbeatable durability, and surgical tool grade hygiene.
Stiff or soft, in every standard size. Pick up one in your size if you need it.
Built-in weight, unbeatable durability and surgical tool grade hygiene.
Gauge, bottle and string, so you can feel the weight before buying one.
The real thing, in the size and length you land on.
This kit is P-tainers only. It assumes you already have a gripper in your size. If you need one, the Stiff Silicone Gripper and the Soft Silicone Gripper both come in every standard size (8 through 16).
This kit only covers length, and every piece comes in the one diameter you pick. If you do not know your size yet, start with The Starter Kit, which sends one demo P-tainer in every diameter along with a matching gripper.
Every standard gripper size, for the highest grip under active tugging.
The same sizes in softer silicone, for all-day comfort.
Tension gauge, collapsible bottle and string, so you can feel the weight before buying one.
The real thing, in the size and length you land on.
Begin with the +5mm and work up. It is tempting to jump straight to the longest one, but more length is not better — it is just more stretch, and starting there tells you nothing about where comfortable actually ends.
Wash each P-tainer with warm water and hand or dish soap before the first wear.
Full walkthrough with pictures and video: How to Wear Your P-tainer.
Give each length a real wear — long enough to sit, walk around and forget about it. Length problems show up over hours, not minutes.
This kit steps in 5mm, which is the same increment our full range steps in, so whichever one wins is a length you can order for real.
This kit does not include grippers, because it assumes you already have one in your size from an earlier order. Use the same gripper throughout so that length is the only thing changing between wears — swapping firmness halfway through makes the comparison meaningless.
If you need a gripper, the Stiff Silicone Gripper and Soft Silicone Gripper both come in every standard size (8 through 16). Stiff grips hardest for active tugging; soft is more comfortable for all-day retaining.
Length and tension interact, so if you plan to hang weight it is worth knowing what that feels like on the length you have chosen.
The Water Weight Kit gives you a tension gauge, a collapsible bottle and a string. Loop the string around the threaded end, clip on the filled bottle, and add water until it feels pleasant. One ounce of water is almost exactly one ounce of weight, so the bottle doubles as a rough scale.
Foreskin retraining is about steady, comfortable tension over months, not about how much you can stand for ten minutes.
Nothing should ever hurt, go numb, or change colour. If it does, take it off and give yourself a break. Remember these are demo pieces: hand wash only, keep them out of hot cars, and treat them as a sizing tool rather than a long term device.
If something does not feel right or you cannot get it to work, get in touch — we would rather hear from you early.
