Categories: Retainers


You will only receive a retainer unless you add a gripper or bulge separately - you need the gripper to use this device!

To see how to measure for your device size, please grab or print our Sizing Guide or visit the How To Measure page

To determine the length of the extended retainer you will need will depend on how much loose skin you have.

  • If your resting foreskin doesn't cover the head while flaccid you may be able to use the +5mm retainer to get a slight stretch while retaining if you have a good amount of slack skin.
  • If your resting foreskin covers about 25% of your head while soft you can use the +10mm retainer.
  • If your resting foreskin covers about 50% of your head while soft you can use the +15mm retainer.
  • If your resting foreskin covers about 75% of your head while soft you can use the +20mm retainer.
  • If your resting foreskin covers about 100% of your head while soft you can use the +25mm retainer.
  • If your resting foreskin covers more than 100% of your head while soft you can use the +30mm retainer.

The interior of this retainer is unique in that it features a funnel-like shape to direct your urine out of the retainer without needing to remove it to pee like most retainers and devices - no need for constant adjustments throughout the day.

The threads built into this retainer allow you to add our weights and accessories effortlessly. You can use ANY of the weights or accessories we sell with this retainer!

Keeping your glans moist with urine or lotion is a proven way to help break down the thick layers of skin that have built up on your glans over the years from rubbing against your underwear and pants. The result of this skin breakdown will dramatically increase your sensitivity and pleasure after only a few weeks of use.

These retainers all have a “frenulum groove.” This groove provides extra space in that area for additional comfort.

Be sure to remove the device and wash it daily with antibacterial soap and water.

Best retainer available!!!

From: Jason - Verified Purchase

If I could engineer a restoration device this would be it! The 3D printing is a game changer for this small industry, and the addition of the custom gripper is next level for us who struggled with baby bottle modification. I would love have this product in labor and delivery units nationwide to show parents just how absurdly ridiculous it is to remove an organ that has a critical function in mans life and the lengths that they go through to repair what was unnecessarily removed.
Thank goodness for stealth retainers and the lives they change!

The extended P-Tainer is a work of genius.

I love my new extended P-Tainer. It's brilliant that you can actually get a stretch while retaining. I finally got to the point of 50% flaccid coverage so I chose the 15mm+ and it is quite perfect. I can wear it all day comfortably and I forget it's even there! I am already going to place another order for the next two sizes. I really love it and I kinda feel naked without the retainer. The material is smooth and comfortable, and the gripper has even gotten so much better than the ones I got years ago. Thank you for this, it's a game changer!

Literally the best tugger/retainer I've ever used

From: Max Muir - Verified Purchase

Long time restorer here. I've been restoring for the last decade, on and off, nothing really serious. I started out with the TLC Tugger, then the TLC-X, then the CAT-II, then had a Fore Restore DA for two years with modest results, but it broke, so I randomly came across this site looking for a replacement.

The biggest problem with all the Tuggers and Retainers I've used/worn, I could not wear them for more than 2h without it pinching, or being in extreme pain, or just randomly falling off because I'm completely circumcised. The 25mm+, with a comfort fit seal, I have worn this the last 2 days for at least 10h each day, no discomfort at all, no need to re-adjust, and after putting some medical tape around the tip of the seal, it doesn't slip off eventually when I urinate.

The added bonus here of the extended P-Tainers is that I'm literally tugging and wearing a retainer with no discomfort. I've even tried to sleep with it on, it's that comfortabl, e (you're not supposed to) but I haven't gotten past the painful erection phase when I sleep. I'm certain that I will be able to wear this device 24h/day eventually. This is a godsend ty.

These Retainers work

These extended retainers work well to keep the foreskin stretched when wearing. This helps stretch the inner foreskin to more coverage over the glans. I only gave a 4 star rating because one of the two extended retainers I purchased had a rough edge. I used some very fine sandpaper to smooth the roughness out and it feels fine now. These retainers are not smooth like glossy plastic, they are made slightly rougher which helps keep the foreskin and gripper in place when worn. They are comfortable and I wear mine for hours at a time. I recommend this product if you are serious about foreskin restoration.
