I love this! I get so much gender euphoria from it, it feels very realistic, and is so much more affordable compared to similar products elsewhere.
Absolutely super comfy they fit really well with thinker and holds everything in place 👍🙂
Pretty good - BUT ! Do not get the foreskin, it is super delicate and broke within 3 days of use.
Hi there,
Thank you for sharing your experience. We're sorry to hear that the movable foreskin didn't hold up as you expected.
The movable foreskin is intentionally made with a very thin and flexible layer of silicone to create a more realistic look and feel. Because of this design, it is naturally more delicate than the rest of the product. Its lifespan can vary depending on factors such as how it's used, the amount of friction, lubrication, and general handling.
We truly appreciate your feedback, as it helps us continue improving our designs.
All the best!
As an STP, this thing worked PERFECT. Zero notes. Trying to pack was a bit harder since I have a small frame and the Axolom harness squished the cup for me. With a bit of finaggling it works just fine, but it can be a bit of an ordeal if you're a first timer like me. Still totally worth the money, especially compared to how expensive other 3n1s on the market are.
This is my first packer, I’m 5’5 130lbs and it’s sized perfectly. bulge isn’t too big, not too heavy in underwear. feels really good :)
