I have been making these pens for about three years for my friends at school, and they love them. These pens are much easier to carry around in pockets and wallets, and they look pretty good, too!
*Note: All pics were taken by my HTC TyTN. Sorry if the quality is bad, but its two megapixels.
Step 1: What you need
A Bic brand ballpoint pen
Scotch or comparable tape
Scissors or an X-acto knife
Paper or some other protector for your desk*
*Note: I am not responsible for any ink spills on your table or computer desk. Nor am I responsible for any damages and deaths that may occur while using sharp objects.
Step 2: Disassemble
Step 3: Cut, trim and tape
Refer to pictures if you need help or guidance. (NOTE: I cut right before the USA part, so it would look nice and clean.)
Next, cut the ink cartridge. Do this fast (scissors may get inky) and tape it up as shown in the pictures. Taping the other end (which you will discard) is necessary if you want to keep from ink getting all over your garbage can.
Step 4: Reassemble
The pen is DONE!!!
