lid for the blind / Lid

lid for the blind
lid for the blind

We improve the lid in order to make the blind use it better.
Braille is engraved on the side of the lid.When the blind unscrew the lid,
they can know what is it in their hands and the instructions of how it works.
So the blind can avoid a lot of problems in life,such as,eating the wrong medicine.
At the same time,braille on the lid also increase the friction force,
which help the blind unscrew it easily.
