There are a large number of cotton sticks being used every day to clean or apply the iodine to the wound. However, the wooden stick which acts as a handle is a big waste. Also, once you open the package, you’d better use up the whole bag of the cotton sticks in a short time.
The Cotton Pen can solve the problems well. Like the bullet pencil, we just need press the button and then the used cotton will be replaced. And of course, it’s easy to reload new cottons into the pen.
