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 (M,L,XL etc), please grab or print our new Sizing Guide or visit the How To Measure page

To determine the length of 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!

How to use the P-tainer

All Sizes of Retainers Include:

• 1 3d Printed Retainer with ¼-20 threaded end
• Optional Gripper (required to use retainer)
• Optional Retainer Bulge - this keeps pee in and creates a natural shape while wearing

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 break down will dramatically increase your sensitivity and pleasure after only a few weeks of use.

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

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