What Makes the Pocket Rocket Different?
Our most streamlined weighted tugging option.
The Pocket Rocket combines three components into one:
- Weight – 12oz of solid 303 stainless steel
- Spacer – Built-in spacer covers the P-tainer threads
- Bulge – Integrated bulge for a natural shape under clothes
No extra pieces to assemble or lose. Just screw the Pocket Rocket onto your P-tainer and you're ready to go.
Shed Glans Build Up
For cut guys, these Stealth Retainer Kits utilize a modular gripping system to pull skin up around the glans to protect those erogenous zones.
- Regain sensitivity: Over time, the skin on and around the glans will shed tougher buildup, returning to a softer, more sensitive state
- Gain coverage: Skin being pulled up will stretch and lengthen over time, eventually acting as a natural barrier on its own
New & Improved Material
We've upgraded our Plastic P-tainers with a new material that's better in every way.
- Smooth matte finish – Provides better grip under the gripper for a more secure hold
- High temperature resistant – Dishwasher safe for easy, regular cleaning

- Same great features – Pee-through design, 1/4-20 threaded end for all accessories, sizes 8-16, lengths from standard to +75mm

Gripper Guide
Your Two Grippers
This kit includes two grippers to cover different situations:
- Soft Gripper (Snug Fit): One size smaller than your P-tainer—comfortable for all-day wear with lighter tension
- Stiff Gripper (Comfort Fit): Same size as your P-tainer—maximum grip if you need extra hold
For 12oz, we strongly recommend the Stiff Gripper for maximum hold at this weight.
Stiff vs Soft Grippers
- Stiff Grippers (clear): Maximum hold for weighted tugging—strongly recommended for 12oz
- Soft Grippers (cloudy): Best for lighter weights or all-day comfort
Need more grippers? They're available separately in our gripper category.
Gripper Sizing Dots
Count the dots around the top of the gripper to determine size
Gripper Line
Keep your skin at or below the gripper line to avoid pinching
Stiff vs Soft Grippers
Stiff Grippers - for high grip during weighted tugging
Soft Grippers - for max comfort during all-day wear
