Description
P-Tainer Demo Kit
Sizing a P-tainer from a measurement is a good start. Wearing nine of them for an afternoon is better. This kit lets you skip the guesswork.
Find Your Size
Why nine
A P-tainer is sized in two directions. Diameter is the number most people mean when they say "size" — how wide the body is. Length is how far it extends, listed as a +mm offset from standard. Both have to be right, and a millimetre or two in either direction changes how it feels.
So you tell us your best guess, and we send that one plus a step either side of it in both directions. Three diameters, three lengths, nine combinations. Wear them, see which one disappears, and order that one.
Nine Combinations
Three diameters × three lengths, centred on your guess
Three Grippers
One stiff gripper for each diameter in the kit
Find Your Weight
Bottle, string and gauge to dial in tension
Made in Austin
Designed and manufactured in Texas
The weight half of the kit
Foreskin retraining is about steady, comfortable tension over months — not about how much you can stand for ten minutes. The bottle, string and gauge are there to help you find the amount that feels right to you. Loop the string around the knob end, clip on the bottle, and add water until the tension is pleasant. One ounce of water is almost exactly one ounce of weight, so once you know what you like, the gauge tells you the number and you know which weight to order.
Already know your size?
If you're only trying to work out how much weight you want, the Weight Demo Kit is the same bottle, gauge and string without the retainers.
How it Works
Everything is labelled. Find the one matching the size and length you ordered and start there — the other eight are your step up and step down in each direction.
Wash the P-tainer and gripper with warm water and hand or dish soap before the first wear.
- Pull the gripper hole over the knob end of the P-tainer, dots facing out.
- Flip the gripper up out of the way.
- Set the dome end of the P-tainer over your glans.
- Hold the P-tainer against your glans by the knob end with your non-dominant hand.
- With your dominant hand, wrap your thumb and index finger around the bottom of your shaft and pull up on the skin while pushing the P-tainer into your body, rolling whatever slack skin you have up onto the body of the P-tainer.
- Use your other fingers on the hand holding the knob to flip the gripper down over your skin.
- Pinch the outside of the silicone to smooth out any wrinkles. The skin should sit flat, with the tip near the circle at the top of the gripper.
Full walkthrough with pictures and video: How to Wear Your P-tainer.
Give each one a real wear — long enough to sit, walk around and forget about it. You're looking for the one that holds without pinching and stays put without you thinking about it.
- Too much tension, or it pinches? Try one step shorter.
- Slack skin, or it works loose? Try one step longer.
- Feels tight around the body, or leaves a mark? Try the next diameter down.
- Skin won't stay rolled up? Try the next diameter up.
The demo kit steps in 10mm increments. If the standard and the +10 both feel slightly off in opposite directions, the +5 between them is probably your size — our full range steps in 5mm.
The string has a pre-tied loop at each end. Loop one end around the knob end of the P-tainer and the other around the neck of the water bottle.
Fill the bottle part way and add water until the tension feels pleasant — around 8oz, roughly half a bottle, is a reasonable place to start. One ounce of water is almost exactly one ounce of weight, so the bottle doubles as a rough scale. A full 16oz bottle is right about a pound.
When you want the exact number, hang the bottle from the weight gauge. It reads to 500g / 20oz.
One heads-up: the string's end loops are just pre-tied knots, and the gauge only has a fixed loop on one end — so to use them together you'll need to untie one end of the string and retie it to the gauge with an adjustable grip hitch.
If you want to feel something genuinely interesting, swing your hips a bit with the weight attached.
Retraining works on consistency, not intensity. This is a process measured in months, and more weight is not faster — it's just less comfortable, and you're less likely to keep it up.
Nothing should ever hurt, go numb, or change colour. If it does, take it off and give yourself a break. If something doesn't feel right or you can't get it to work, get in touch — we'd rather hear from you early.
