Stain Remover On-The-Go
The assignment was to design a stain remover that can be taken with you and can be used anywhere.
I have designed a stylish highgloss pen-sized stain remover that can be discretely taken in your pocket.

The specially designed valve makes it impossible to leak whenever the pen is not used, as soon als the tip is pressed the liquit comes through the tip.

When the pen is not in use the rear reservoir is connected to the front reservoir, as soon as the tip is pressed the rear reservoir is closed, then the front reservoir opens and drains through the tip, so there are always the same amounts of liquid coming out when the tip is pressed.
