I will show two ways to always carry duct tape in your pocket. The first method is circular in your pocket and the second is flat, sorta like a credit card.
P.S. This is my first Instructable so please spend a minute to give me feedback. Thanks :-)
Step 1: Materials
If you are going to do Variation #1, then you need a BIC pen.
If you are going to do Variation #2, then you need a card. Like an old credit or library or some membership card. You could also use those credit cards that you get in the mail that you don't activate.
Step 2: Variation #1
Now cut the barrel a little longer than the actual width of the duct tape you are using. If you want to you can file down the ends if you didn't cut too well.
Now just wrap the duct tape carefully around the barrel of the pen, and make sure it is all straight.
If you want you can make some pieces of plastic or cardboard or something in a circular shape and make like some "guards" around the duct tape.
Step 3: Variation #2
This one you can stick in your wallet or your pocket.
