Adhesion Tab
Product FeatureThe smooth part at the back of the prosthetic where adhesive is applied. To attach the prosthetic to your body, apply adhesive to the adhesion tab, press it to your body, and wait until it dries. This creates an ultra-realistic look by allowing you to wear the prosthetic without harnesses, straps, or underwear.
Adhesive
AccessoryIf you decide to use adhesive instead of a harness or specially designed underwear, you must use medical-grade adhesive suitable for silicone products. We strongly recommend well-known adhesives such as Pros-Aide or TELESIS 8 SILICONE ADHESIVE. Each person's skin can react differently—if you experience a rash, burning, or other unpleasant sensations, remove the prosthetic and clean the adhesive immediately.
Learn More →Adhesive Remover
AccessoryIf you use adhesive, it's necessary to purchase adhesive remover as well. Due to its thick and sticky consistency, water alone isn't enough to remove adhesive. Apply the remover, wait a moment, wipe it off, then wash with water. Adhesive remover is designed for contact with human skin, so it's completely safe to use.

Binding
PracticeThe process during which a person flattens their chest to achieve a more masculine physique. It's a very common practice for FTM transgender individuals to start binding their chest before deciding whether to proceed with surgery.
Binder
ProductA specific elastic or non-elastic bandage used to wrap around the torso and flatten the chest as much as possible. FTM individuals commonly use various items as binders—cloths, bandages, sports bras, compression shirts, and specially designed undergarments—to flatten the chest and reduce breast appearance.
1 Term
Cup of STP
Product FeatureThe cup of a stand-to-pee device is located at the back of the prosthetic and is designed to collect urine. This allows you to use urinals without any leaks or other unpleasant situations.
1 Term
Extension
Emisil ProductA thick, stretchy sleeve that fits snugly around your penis shaft. Made from lifelike, firm yet squeezable material with an extremely realistic epidermis layer that replicates real skin texture. The finest details like arteries, veins, and wrinkles are clear and visible. Available in two sizes and 16 different skin shades.

F2M / FTM
IdentityRefers to people assigned female sex at birth based on their genitalia, but who identify as gender-neutral or male. These individuals often transition from female to male through hormone therapy, using packers, STPs, binders, double mastectomy, and/or sex reassignment surgery. While "FTM" remains popular, "transmasculine" is considered more respectful terminology.
Flaccid Packer
Emisil ProductDesigned for daily use, these FTM prosthetics are highly recommended for those looking only for a packer. With a focus on ultra-realism and comfort, they're ideal for wearing in your pants all day, every day. All models feature a 360° scrotum with movable floating testicles. Each Emisil packer is nearly indistinguishable from a real penis.
Shop Flaccid Packers →Floating Testicles
Product FeatureAll Emisil products have moveable, realistic-looking testicles. We designed floating testicles similar to real-life male testicles—silicone balls filled with special gel that allows them to float freely when squeezed, providing an extremely realistic feeling.
Funnel
Product FeatureA part of the stand-to-pee device that collects urine and directs the stream through the shaft of your penis prosthetic.
2 Terms
Gender Dysphoria
IdentityA condition causing distress and discomfort because a person has genitalia of a different gender than they identify with. For transgender individuals, it's the feeling that your genitalia is mismatched with your gender identity. Transmasculine individuals often feel they are missing a part of themselves due to not having a penis. While some choose surgery, many prefer wearing packers or STPs. Emisil is known to help with gender dysphoria because our products are ultra-realistic both visually and in feel.
Girth
MeasurementWhen choosing a prosthetic, it's important to consider not only length but also girth. Girth measures the circumference around the widest point of the shaft. This helps you know the exact width of each product.
2 Terms
Hair
Product FeatureAt Emisil, you can get your prosthetic with hand-punched natural human hair. The hair is punched manually to create a more realistic look, hide the edges of a glued prosthesis, and avoid unwanted attention. It creates the appearance that hair grows naturally. Choose from 16 different colors for the perfect match.
View Hair Options →Harness
AccessoryA specially designed undergarment to secure your prosthetic. There are many style options including briefs, boxer briefs, open back briefs, and button-fly briefs. If you're very active or prefer not to use adhesive, a harness is the best option. When choosing, don't go cheap—quality matters for functionality and comfort.
Wearing Tips →1 Term
Jockstrap
AccessorySimilar to a harness, a jockstrap is an undergarment designed to secure your packer comfortably. There are multiple producers and options to choose from. We suggest choosing a trustworthy company that produces jockstraps from high-quality materials.
2 Terms
Length
MeasurementWhen buying a packer or STP, it's very important to choose the right size. We offer various options with measurements in each product's description. Length is measured from the adhesion tab to the tip of the penis.
Length Insertable
MeasurementThe insertable length is especially important for pack and play prosthetics. It's measured from the tip of the penis along the shaft to the beginning of the scrotum.
6 Terms
Packer
ProductA phallic object worn by transmasculine individuals to create the appearance of a penis in underwear. People use different objects—from DIY sock packers to lifelike penis prosthetics that can be used for packing, playing, and even peeing. Each person is looking for different things, so we offer a wide selection.
Shop Packers →Pack and Play

Shop Pack & Play →Packer Erect
Emisil ProductErect packers are mainly designed to pack and play. The design is created for maximum comfort during intercourse. At our shop, you can choose various erect models—very erect, pointed down, or extra-large erect prosthetics.
View Erect Models →Passing
IdentityWhen talking about transgender individuals, "passing" means that a person looks visually and sounds like the gender they identify with. For a transgender person to pass as the gender they identify as is often considered very affirming.
Plastic Rod
Product FeatureOur erect products can be purchased with a plastic or silicone rod. With a plastic rod, you can bend the shaft down, release it, and it will stay in position. The rod is very light, causing no issues at airport metal detectors. May exhibit some noise when flexing due to friction of plastic ball joints.
Pleasure Pocket
Product FeatureAn optional addition to erect prosthetics that provides a possibility to receive additional stimulation during intercourse or while wearing the prosthetic. The pleasure pocket is textured inside to create suction and stimulate the clitoris, creating extra pleasure for the wearer.
10 Terms
Scrotum
Product FeatureAll Emisil penis prostheses have movable testicles. The scrotum contains silicone balls sunk in special gel, allowing them to float freely when squeezed for an extremely realistic feeling. When pressed, you can see color changes and differences between the layers.
Shaft
MeasurementThe shaft is the part of the prosthetic starting at the tip of the penis and ending at the beginning of the scrotum. Usually, the insertable length equals the shaft length.
Silicone Rod
Product FeatureUsually integrated into erect series and also added to STP devices. With STP devices, the silicone rod can be removed and inserted when needed. Unlike the plastic rod, if you bend a silicone rod and release it, the shaft will return to its original position.
Rod Differences →Skin Color
Product FeatureSelecting the correct color for your prosthetic can be tricky. We created reference points using real people's skin colors so you can compare with your own skin for maximum compatibility. The color range is made according to body colors of people from various nations. Keep in mind that colors shift in different places for ultra-realism, with added details like veins and freckles.
