Easily corrects male genitalia to look like female genitalia!
Until about 10 weeks into pregnancy, both male and female are close to the female genitalia.
The male labia minora closes and becomes a scrotum, and the clitoris (clitoris) grows and forms into a penis.
The penile minor girdle (back muscle) of the male genitalia is considered to be a remnant of the closing of the labia minora and other parts of the genitalia.
Amful's DuckTack is the world's first patented corrector that holds each male organ in position for the female organ.


DuckTack's category?
(1) Does it fall under the category of adult toys? (2) Does it fall under the category of medical devices? (iii) Does it fall under both?
*1) DuckTack is not an adult toy (SEXTOY), etc., and we insist that it is not a product that offends public order and morals.
The patent will not be granted to a product that is offensive to public order and morals. (We respect the decision of the Patent Office)
*②DuckTack is not a medical device to treat specific diseases.
The DuckTack is intended to temporarily correct the appearance of a healthy and normal male genitalia to resemble a female genitalia in everyday life (similar to a bra, hairpin, etc.). (similar to a bra, hairpin, etc.).
...Being transgender or crossdresser is not a treatment because it is neither a mental nor a physical illness.

Both male and female genitalia vary in shape and size from individual to individual.
For this reason, Amful DuckTack has been patented for its 7-pattern structure!
function number
(1) Fix and correct the scrotal surface skin of the male genitalia to the position of the labia minora of the female genitalia.
(2) - A. The glans of the male organ is fixed in the position of the clitoris (nucleus pubis) of the female organ to compensate for the position of the clitoris.
-B. The glans of the male genitalia is fixed in position at the urethral opening of the female genitalia to compensate.
(iii) The vulva is imitated between the left and right labia minora.
Advantages of Duck Tuck
The appearance of the female genitalia can be corrected.
The clitoris (glans), labia minora, and vagina (scrotum) can be touched with one hand at the same time, making it easier to approach the female experience with a different sensation from that of the male genitalia.
...Easily sensitive to sexual sensations. (Individual differences exist.)
... easy to have a dry orgasm like a woman.
The vagina is simulated between the central support bars, so if there is room in the scrotum, a simulated insertion experience is possible.
It is also possible to urinate similar to a woman while wearing the device.
If you have a pseudo foreskin, you can also reproduce a clitoral foreskin.
Once you get used to it, you can put it on in about 5 seconds.
...Easy to walk beautifully because the legs and genitals are less likely to rub against each other.

Cons of Duck Tuck
May experience pain due to mounting.
Testicular function may be impaired because the testicles are fixed inside the body and are susceptible to high temperatures.
. may decrease erectile strength.
The production of male hormones may decrease and feminization may occur.
/ May cause skin irritation, inflammation, and itching.
This is the first product of its kind in the world and there are no case studies, so there is a possibility of unforeseen adverse effects.
This product is intended for those who desire feminization, not male genitalia.
If you do not understand and accept the disadvantages and risks, please do not purchase or use this product.

Type A Function ① ②③
Clitoral-oriented model (for advanced tuckers)
The appearance is the most realistic of the series.
The clitoris, a sexually sensitive zone, is emphasized in this type and is easily sensitive.
It is a type for intercourse and masturbation like a woman.
The clitoris, labia minora, and vagina are also compensated and imitated and balanced in this type.
When it is well attached, it is so difficult to distinguish it from the female genitalia in a thinly mosaiced photograph.

Type B supports penile storage by holding the glans in place with a clitoral fixation pad.
It is recommended that those who do not have good penile storage or those with a large glans practice with the B type.
Attachment is assisted by an elastic strap, which reduces the amount of tape used and the burden on the skin.

Appearance-oriented model (for tack intermediate users)
We pursued an appearance similar to that of a female genitalia.
Types A to C tended to shift slightly above the real female genitalia,
When used in conjunction with a waist nipper corset, it is now possible to correct to the position of the real female genitalia as far as possible.
Especially in the standing position, it could be mistaken for a real female genitalia.
It is the only type in the series that can be corrected like a labia minora.
Urination can be done like a woman by pulling the cord from the rear and adjusting it as needed.
It can be worn without tape, so it is gentle on the skin even when worn for long periods of time.
(With the use of auxiliary tape, a urethral opening can be created between the labia minora for downward urination.)
The wearer must be familiar with the internal storage of the penis.
E type Function ① ②③
Function-oriented model (for advanced users of tack)
The first in the series, each function was pursued comprehensively.
In the female genitalia, the clitoris and urethra, which are sexual zones, are separated, but in the penis, the glans and urethra, which are sexual zones, are integrated.
Type C corrected the penis as the urethral opening, while types A, B, and D corrected the penis as the clitoris and could only correct for either.
Type E is characterized by the correction of the glans crown as a sexual clitoris and the glans urethral opening between the labia minora.
The labia minora compensate for the scrotum as well as other types.
The position and role of each part can be corrected to resemble real female genitalia.
The clitoris, urethral opening, vagina, G-spot, labia minora, and each area are comprehensively corrected to resemble female genitalia.
(1) Fix and correct the scrotal surface skin of the male genitalia to the position of the labia minora of the female genitalia.
(2) - A. The glans crown of the male organ is fixed and corrected to the position of the clitoris (nucleus pubis) of the female organ.
(2) - B. The urethral opening of the male genitalia is fixed at the position of the urethral opening of the female genitalia to compensate.
(iii) The vulva is imitated between the left and right labia minora.
Aim for feminine urination.
Less likely to reach masculine orgasm and more likely to reach feminine dry orgasm
This is for short-time wear as it is designed to cause pain when worn for long periods of time.
Both functions of the female external genitalia, urination and sexuality, are approached as in the female genitalia.

A single labia minora support bar with no vulva.
The clitoris (glans) is separately fixed with tape or rubber.
It is for those with a small scrotum.
DackTack can easily correct the realistic appearance of the female genitalia without the need for sex change surgery.
New proposal for transgender women, cross-dressers, male daughters, transsexuals, and all those seeking to become women!
*Please beware of imitations.
DuckTack has patented seven possible structures to correct the appearance of the male genitalia to that of the female genitalia.
Dozens of types can be designed by combining these seven patented patterns.

It is infinitely impossible to create a similarly effective product without using this patented structure.
Therefore, if a similar product is available, the possibility of ineffectiveness or patent infringement is extremely high.
Also, we do not know what is contained in materials that have not been tested for safety.
Many industrial resins are not designed for prolonged contact with skin, and some contain carcinogens and other harmful substances.
Even ABS resin, which is considered to be free of skin irritants, contains chemicals such as styrene, acrylonitrile, and butadiene, which, when released in specific concentrations, raise concerns about carcinogenicity and neurotoxicity.
There is concern that hazardous substances may leach out, especially when lotions, adhesives, or tapes are used.
DuckTack is the world's only external genitalia corrector made of patented construction and safe materials.
