in order to let the students can afford such a pen, i plan to material scrap and old pen. first the scrap iron coated with color liquid, then put it into a copy of ink and ink color can change things, this thing is very small, with sesame almost to fit in a pen liner, the paint discoloration liquid iron will also be made into a pen. old pen to complete, thorough clean, to tie a small hole in the ceiling of monlchamus placelet the ink flow in. this pen has two heads, one is a fine head to write regular words, a thick head, can be used to color, the two written by a small button control switch.
don't worry about the ink in the pen liner too much or too little, much it will automatically absorb some,less of it will be released automatically ink, a word will keep ink just pour advantage. if you want to change the color of the ink, press the pen top, then color pen pen pen color is the will, and now youwant to ink color...... there are a lot of its benefits, such as leave your body a certain distance will sound, so as not to forget to take it when you go to school, the sound will become the morning wake you up bell, and during the break, it also can sing beautiful songs make you relaxed for a while, more energetic the next class.
this pen is i want to invent, you feel it?
