Fits in a standard tape dispenser
Number of Items: 12
First of all, I like the width of this tape when I don't need the full width of standard 20mm. It's great for delicate projects and minimizing taping over two-sided sublimations like keychains. There's just enough adhesion and it comes off cleanly so it does the job. If you don't need the full width of 20mm, this is a great value. For those looking for a compatible dispenser, these rolls fit into a standard weighted Scotch tape base like the C-38. There will be room around the core because these rolls have a larger diameter, and room on either side because the rolls are thinner than standard Scotch tape, but once you pull the tape onto the blade, the roll remains taut and it's easy to remove pieces of your desired length with one hand.
