Step 1: Materials Needed:
2. duct tape (I used Black since that's the only Duct Tape lying around in my house. Also, if you have Grey that would be PERFECT because that's the color of the cartridge...well, if you care about that sort of thing...if NOT then just use any kind of Duct Tape color)
3. Scissors (for cutting of course)
Step 2: Let's Get Started:
This picture shows the back side of the cartridge. The tape is on the TOP (but NOT touching the label, don't do that...unless you don't care about messing up the label) and the SIDES.
