AXOLOM Argos Lifelike FTM STP Packer - 4.7" Shaft Cut
AXOLOM Natow Compact STP Packer - 4.5" Shaft Cut
The feeling, the look and the usability is amazing. Very easy to pack, awesome for play. The feel of it is as real as it gets!
Still need to see how it handles more wear over time but so far amazing experience
About me:
I am 171cm tall and my weight is about 72kg. I have light skin colour and i chose C4. This is my second "fake penis", i already have STP Freely and i wanted to get second one (hopefully longer and shofter). I paid more to get moving balls and foreskin.
Pros:
- it is very SOFT and squishy but the cup is a little bit firmer which is helpful
- Lifelike. I has nice details around the head (some wrinkles and the way the foreskin is attached to the head is realistic). Shaft has veins and balls has the middle line. Very nice appearance.
- The soft silicone makes it nicer to pack with, it doesn't create too muck pressure against sensitive areas. It doesn't look like a hard-on when packing
- long shaft makes having sex easier, so it doesn't slip out in the middle of the fun
- colour of the stp is nice, the C4 is a bit too dark (very little) for me but generally i like how it doesn't look like it screams "look at me!" when using it. It looks just natural penis without unnatural glow or angry pink head (which some stps have)
Cons:
- teksture feels like sticky silicone, so i recommend powdering
- have to pack up because it is VERY long shaft. Shaft between legs would cause fast wearing down
- need's some kind of harness or special underwear to stay in place. I also protects the product agains friction
- it is harder to pee with than with Freely because of the softer silicone. But after few try at home i learned how to use it
Moving balls and foreskin:
- I love the foreskin, it is very thin and showt and it moves very easily
- i don't know yeat how foreskin will last without breaking in daily use yeat
- balls are fun to play with
- paying extra 50$ was worth it
- you cannot move the foreskin over the head, it is attached to the shaft from the head (any dirt cannot go under the skin because it is closed). But it is strechy enough to pinch between fingers and move around good amount along the shaft
Very realistic and works best with the flexit harness. Honestly helps the dysphoria a lot.
