The EZP by Transthetics is a one-of-a-kind STP that doubles as a packer. It is available in 3 color shades, 2 sizes, and you can choose between cut or uncut. This STP is very easy to use while peeing, however, packing is another story! There are a lot of pros and cons to this STP which will be discussed in this review.

The Great

  • Very easy to use 
  • Attention to detail. The peen itself is very realistic looking
  • Choice of cut or uncut!
  • Smaller size is great for kids/teens!

The Not-so-Great

  • Not Budget Friendly. This is a more pricey STP than others. 
  • Can be difficult to pack with
  • Darkest skin tone isn’t great


The EZP comes in a soft black cloth bag with instructions. 

Each shipping box and custom form is different depending on the company and country. If you are unsure if the company you are ordering from has discrete shipping, be sure to contact them prior to ordering. 


The EZP is available in 3 different colors. Honestly…. I really like this company and I just wish they offered more colors. Their C006 “darkest shade” in real life is really not that dark. It’s not very accessible for a lot of people and that’s disappointing. There are some companies out there making 7 skin shades, others have more than 100 options! It’s absolutely doable!

C002 – Light
C004 – Medium
C006 – Dark


Regular EZP:

Length end to end: 6″/15cm
Length of shaft (underside): 3”/8cm 
Length of cup (top): 3”/8cm 
Width of cup: 2.4”/6cm 
Weight: 4oz/110gr 


Dimensions (Junior):
Length end to end: 5”/12cm
Length of shaft (underside): 2.5”/7cm
Length of cup (top): 2.5”/7cm
Width of cup: 2.4”/6cm
Weight: 3oz/90gr

The Junior is great for kids, teens, and people who are smaller. I’ve used both of them and prefer the regular size. The smaller size is significantly smaller and a little hard to place in the right position to pee in. The shaft is smaller so it makes it a little tough to figure out (but it is doable).

Material and Feel


The EZP is made out of platinum-grade silicone and has an added layer of paint in order to emphasis certain parts of the peen to make it more realistic. This prosthetic is not sticky/tacky to the touch, however, it can attract some dust/dirt/hair (which is easy to remove). The paint job is very realistic, however, it is important to note the paint does not last forever. If you use this STP daily, the paint will slowly fade. The peen itself doesn’t look bad when the paint has faded.


Ehhh, this is where it gets a little tricky. If you’re looking for a prosthetic that looks realistic and feels realistic in your pants, the EZP might not be the answer. It’s a great STP, however, packing with it can be a little awkward. You have to keep it straight and pack it either upwards or downwards. It doesn’t look horrible in pants (or undies), however, it doesn’t feel like it’s part of you

Please note: it is recommended to NOT fold the EZP to pack with it as it can damage the prosthetic.

This was the first STP I was able to use no problem without any leaks on the multiple occasions I tried it. It was also the first STP I was able to use in public! (back in 2015). Needless to say, this STP is great for it’s intended purpose. Peeing with this is very easy. I do still recommend that you test it out in the shower or standing in a bath so that you don’t get pee all over yourself. Practice makes perfect!

There is a no spill-lip that heps prevent the pee from falling out of the cup! This is a fantastic feature to have (and if you are looking for any STPs in the future, I recommend always going for one with a spill-lip!)

And obviously, some STPs will work for me and others won’t for you. Everyone’s anatomy is different. This is just from my personal perspective.

If you have a bigger body: I do not recommend this STP. The shaft is too short (which means there might not be enough room for pee clearance).

Real Feel Test™

Visual Realism 4/5

Visually, the independent parts that make up the EZP are very realistic. The shaft, the head, the balls, all great! However, this prosthetic is shaped in a flat way, and peens that are connected to people don’t look like this. But, visually, wow. The details are fantastic and you can really see all the little lines that make up the peen!

Touch Realism (Through Pants) 2/5

If you or someone else were to grab your peen through underwear, it would feel like an erect penis. If you squish it, the inside is obviously carved out (since it’s an STP) and it does feel like a hallow peen.

Touch Realism (Skin-Like) 1/5

This does not feel like skin. It’s very soft and you can feel the details of the veins and little lines in the shaft and balls. However, the material itself does not feel like skin. 

Cleaning and Care

I recommend cleaning this product before and after each use. 

The 100% silicone component makes this STP easy to clean and sterilize. The easiest way to clean this product is with hot soapy water or by sticking it in the top row of the dishwasher. If you need to sterilize this product, put it in a boiling pot of water for 3-5 minutes. Because this product is made of 100% silicone, boiling it is 100% safe. 

If you find that the prosthetic is tacky/sticky after cleaning it, I always recommend using cornstarch (or other rejuvenating powders) to maintain a smooth and silky texture. If you have one of the darker skin tones and you don’t want to put white cornstarch on it, add a little coco powder to the cornstarch to offset the color.

*Please do not use talcum powder (most commonly found in baby powder), it has been associated with different types of cancers, mostly ovarian cancer. We have a full article on the dangers of talcum power here.


I recommend using the original packaging. Place this product in a cool, dry, and dark place, like a dresser drawer. Do not store it with other similar-material products as those eventually can start to morph together, which is really not fun. Sometimes, these products secrete an oily texture and a canvas bag will help absorb this moisture.

Durability 5/5

This is some very durable silicone. If you take care of it and don’t fold it, this will last you YEARS.

Packability 2/5

Not the best in terms of packing, but it can be done.

Budget Friendly 2/5

$195 is a little steep for an STP. 

Urinal Friendly 5/5

Very easy to use and looks realistic at the urinal.

Final Thoughts

In terms of functionality, this STP is great. It’s made for peeing and it really is easy to use.

Although this STP isn’t perfect and there are many more after it that have come, Transthetics as a company makes amazing, detailed, realistic prosthetics. I recommend checking out the Joystick if you are looking for something for sex.

I’ll be honest, when I first got the EZP back in 2015, I was ecstatic. At that time, there weren’t any STPs with a similar shape and It was the first STP that I was able to use in a public bathroom. All other STP attempts in public were a disaster. So since that review, things have changed in the prosthetic world and I have found better STPs. Just keep in mind this means the review video will be a little different than this review!
