They give space for the ties and the ring is in the right spot no complains.
Unfortunately, the quality is poor.
The buttons on the underwear fell off as soon as I unpacked them.
And after washing them eight times, there are already holes...
Smooth and stretchy. They work beautifully with The Thinker. If you are looking to use an STP covertly/handsfree, keep in mind that you may need a harness as well. The boxers do not hold the packer flush enough to my body that I can use it without holding it or wearing a harness.

I think these are my favorite boxers for packing. Very versatile, great fit, nice fabric. I would love to see one made with an extra pouch, instead of the elastic for regular packing, then these would be all I would ever buy.
I love this STP and have had no issues. It took a little while to learn how to use it but it was totally worth the wait. Great product I will definitely buy another style down the road.
This is my first quality stp prosthetic, as i was originally using a cheap cal exotics one. The material is very nice and soft yet sturdy, which I like in comparison to the tough silicon on cheaper stps. But, what I dont like about it is that the color is incredibly different on the listing than in real life. I’ll attach a picture of it. as a pale person, it’s kind of disappointing to have the prosthetic be so dark. also, in order for any stp to work, the back of the cup has to be placed all the way back to the gooch to avoid spilling. this one, in the position that it can be used as a packer, it is unusable as an stp, and in the position that it can be uses as an stp, i packs way too low where your bulge is just like a thick two inch extension to your lips. its usable, but for the price, super disappointing for the first time ive spent real money on something like this.
I’m a 5 foot trans guy and it’s hard to find packers that are an appropriate size and comfortable. This one is perfect. It’s realistic. It’s a perfect size and it’s extremely comfortable often times I forget I’m even wearing it would highly recommend.
This packer is great so far, nice and squishy, and it looks pretty realistic. It lays fairly naturally too, it looks like a soft bulge, not a semi lol
Very pleased so far with it.
I was going back and forth on which one to get and I do believe I made the best decision I am beyond thankful for the confidence boost this website never fails me
The packer didn’t even arrive at my place eventhough I was home the whole time. The local deliverer sent it right back which I do not understand. GLS is a very unprofessional deliverer. I kindly ask for a refund.
