These are SO cute and really easy to make.
1
Gather your materials.
2
Pull out the little plug in the back of the pen. This is the hardest part. You can use pliers to squish it out.
3
Now put the cap back on as sort of a template for where you should cut. About two centimeters back from the pen cap, cut the pen. Sorry the picture is blurry!
4
Now put the "plug" back in the pen.
TADA!
