STP Freely

by TG Supply


Transguy Supply's signature stand-to-pee device.

We spent countless hours researching and testing STPs in order to design a device that was attractive, functional, and affordable. Sturdy enough to hold its shape when you're using it, but soft enough to pack comfortably all day long. The STP Freely is never sticky, even after washing, and will never need powdering.  

Pair this STP with a Cake Bandit Harness that can be worn under any underwear or the Cake Bandit STP Boxer Briefs which we’re designed specifically for using an STP.

100% Body-Safe Silicone

  • Shaft Length (measured from bottom): 3 inches.    
  • Cup Inner Width: 1.25 inches.
  • Cup Outer Width: 2 inches.
  • Cup Inner Length: 3.5 inches.

    Silicone may be cleaned using any one of the following methods:

    This STP packs easily and can be packed up or down. 

    Pair with any Cake Bandit Harness for the best fit.

    Note for first-time users, we strongly recommend that you practice in the shower before attempting to use it in public. Even if you have had success with other STPs in the past, every STP is different and requires some getting used to.

    Euphoria in a box, get it!!

    My very first STP was this one. Bigger than I expected, but I didn't mind. Nice to pack with, easy to use pee-ing wise, and easy to clean. That silicone is remarkably soft- and wearing this w a harness gave me amazing eurphoria. Plus, the package arrived VERY quick. I live in the USA ofc, but it only took a week!!

    Big Euphoric Feels

    This is my first STP/Packer combo I have ever used. Before this, I was a long adherent to pinning a packer pouch under the waistband of my boxer briefs, and have used STP devices before, but only the silicone funnel ones that are heavily marketed for active women on the go. The pinned pouch deal is great, except for a few things. 1, I still needed a separate STP device. 2, It would create issues with the fit of my pants, dragging the waistband downward, and 3, sometimes the pin would come undone, which is a total catastrophe waiting to happen.

    So, after some light researching online, I decided on the STP freely in 01- the lightest tone, along with a Cake Bandit harness in black, in XL. (For reference I am 5’5”, approximately 195 lb).

    The STP Freely is a beautifully made packer and it fits well into the Cake Bandit harness. The silicone is high quality and thick. The urethral hole is large- but not ridiculously so. There is a testicular area which doubles as the main cup of the funnel. The rim of the funnel is thick and wide, allowing for a pretty darn big seal around your existing… er… plumbing. The testicular area is made of the same thick, high quality silicone. It’s thick enough to not collapse when you’re in action, but it’s also squeezable and flexible, which comes in handy! I must note, it’s not thick enough to be ideal for penetrating a partner.

    I’m still a novice at STP/packer combo life, and I’m still practicing in the tub, making adjustments to the fit, training myself to control my flow better, and learning the best funnel emptying techniques (squeezing my balls seems to be the winning technique so far! Maybe not scientifically accurate, but it does make for a laugh).

    I’m also still working on adjusting it in my pants. I didn’t really have to think about this with the old tried & true limpy packer, but if I don’t position myself correctly, I can look quite a bit excited with the Freely. Fortunately, it’s not too obscene.

    With each time I use the Freely, I get better at it. It certainly gives me a great amount of euphoria to be able to stand to pee. While the low price in comparison to others on the market might seem like a red flag for those looking for a legitimate, functional prosthesis, please don’t worry. This STP does a great job balancing form, function, quality, & cost- a real saving grace for trans guys who might face financial barriers. To me, it’s more than just a novelty item. It has the look, feel, and function of a decent prosthetic.

    It’s worth a try! Don’t forget the cake bandit harness.

    Super stoked

    This is my first packer. I have spent years researching and debating with myself off and on if I should/want to get a packer, let alone an stp. I finally decided to get one and that I wanted to get an stp since I live in a very conservative state and using the women’s room has become harder. I’ve only had the freely for a few days and I am so happy with it. I’m still practicing in the shower but feel confident enough to try aiming for the toilet tomorrow. There was like an excess ring of silicone on inside of the bottom of the shaft that would plug up the hole when I first tried it and wouldn’t let any liquid flow out (suggest first trying your stp out by running water from the tap through it). I stuck some needle nose pliers through the hole and it flows perfectly now. 10/10 recommend

    So euphoric!!

    This is my first packer or STP and so far it seems like it works super well as either! I still need a little practice with the STP part but the cup is a great size and it’s easy to position in the right place. And as a packer it works really well with the cake bandit harness! (Extra points for posting that video on Instagram on how to use the harness!) I’ve always been unsure of whether I would like a packer or STP but it literally makes me so happy. It’s a great size so it’s not too dramatic but it’s just right for me.
