Telling Cap / Product (Help & Support)

This product is mainly aimed towards people who are visually impaired. Visually impaired people have difficulty identifying and choosing a beverage. However, "Telling Cap" will solve these problems.
Caps are generally threaded for ease of opening a bottle by utilizing friction. But, people who are visually impaired have no way of knowing what they are drinking.
If you engrave braille instead of having a threaded caps, people with vision impairment will be able to distinguish their drinks.
Due to the shape of braille, people should be able to open a bottle with ease as if they are opening regular threaded caps.
