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.
I didn't expect the STP to be so easy to use as I've never used one before. This was perfect! It packs well and pees well! Can't wait to try out the play portion since I also bought the rod.
Very satisfying to wear. It looks great. The balls are nice to squish and play with, the head is soft but firm, and the shaft is also a bit squishy but perfectly firm. Haven't had sex with it yet, but the pleasure hole does not fit as well as I hoped (as someone with substantial bottom growth), but that was expected based on other reviews, so I'm not too disappointed. The flexit harness is perfect with it. I enjoy the upwards angle of it. It's also very flexible. It's hard to pack, which I also expected, but it's not impossible. That's why I got the mini. It's a good size for my small girlfriend and it would be easier to pack than larger sizes. It'd still be better to just use a regular packer on the daily instead of this though, since this one is pretty erect. It's easy to clean as well. Lots of happy feelings and definitely a large relief of dysphoria while wearing it.
Wasn’t a fan of it. Don’t like how it folds and flattens out. Probably won’t use it but obviously can’t return it

Very good stp. Fits better with my anatomy. A little awkward to pack with but it works.
Very light, sits comfortably in underwear and creates a nice but not massive buldge.
