The DuckTack D type is an appearance-oriented type that suppresses bulging and corrects labia-like split.

Wear the special waist nipper corset and attach the DuckTack D type with elastic straps.
By wedging the DuckTack into the labia, it is possible to correct for labia-like clefts.
Split lines can be expressed on underwear and swimsuits. (Large genitalia and small subcutaneous fat may have difficulty with the appearance of split lines).
Basically, it is intended to be worn without tape, but if the scrotum forming the labia minora is small, tape may be necessary as an adjunct.

Solves the uncomfortable problem of tucking.

When urinating with tape tucks or adhesive tucks, the adhesive part easily peels off, and urine and sweat can cause bacteria growth and foul odors.
Redoing tape tucks and glue tucks in the bathroom on the go is time consuming and public.

With DuckTack, you can wash the bidet while wearing it after urinating, keeping it clean.
A clean bidet wash and wipe with a hand towel will keep you comfortable even in summer.
Once you get used to it, it takes about 5 seconds to put it on, and you can even put it back on when you are out and about.
The lifestyle of a male daughter/pre-surgical transgender woman will change.

If you do not understand and accept the disadvantages and risks, please do not purchase or use this product.
*Returns to the original male organ when the duck tack is removed.

DuckTack uses materials that have passed biocompatibility certification

The resin used in DuckTack has passed ISO 10993-5, ISO 10993-10, and ISO 10993-23 certification for skin contact, which is also used in medical devices.
(The above means that the material itself does not contain any toxic ingredients, and this does not apply to friction with the skin, tightening, or bacteria that may adhere to the surface when the surface is unsanitary.)

DuckTack D type, ultra-fine resin fiber mesh structure

Silicon rubber molded in a mold is flexible and pleasant to the touch, but it is not suitable for Tack due to its weak corrective power and durability problems such as tearing and cracking quickly.
In addition, ABS/plastic and metal-based materials have corrective power, but fit poorly and are painful, and there is concern that they may rupture and cause injury depending on movement.
DuckTack has a two-layer construction, with the interior slowly and carefully knitted with resin fibers and a mesh structure that provides both flexibility and durability.

The surface is made of ultra-fine resin fiber, which is non-slip and has a good feel to the touch.

Smoothness has been slightly improved by further thinning the ultrafine resin fibers to 0.08 mm.

(i)Amfulle Shop <Official>The world of fashion is constantly changing, and it can be difficult to keep up. But there are a few key trends that have emerged in recent years. One of these trends is the increasing popularity of sustainable fashion. This means that more and more people are choosing to buy clothes that are made from eco-friendly materials and produced in an ethical way. Another trend is the rise of "athleisure." This is a style of clothing that blends athletic wear with everyday fashion, allowing people to be comfortable and stylish at the same time. Finally, we're seeing a growing interest in vintage and secondhand clothing. This trend is driven by a desire for unique pieces and a rejection of fast fashion. These are just a few of the many trends that are shaping the fashion industry today.

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.
