Works well for sublimation

I use this to sublimate cloth items. It works as well as the name brand.

Perfect size works well
Number of Items: 4
The thickness is perfect. The quality is great very doable and holds very well. Whenever you wrap it great value for the money. I’ve tried other ones and this one is the best so far.

Does not fit in any tape dispenser
Number of Items: 4
While the tape itself is good I haven’t found a dispenser that works with this tape. For that reason when it’s gone I will try something different.

Great price point, value, quickness to ship
Number of Items: 4
Arrived well packaged, does what it’s intended to do. Not overly sticky but sticky enough to adhere to surfaces and hold things in place. Doesn’t burn or melt and doesn’t affect the pieces of sublimation it covers. I like the thickness over the thin tape as it’s easier for me to manage, and my dispenser holds the thicker tape. Has saved me when I’ve ran out of tape for projects and needed and immediate replacement overnight. I work 12 hours overnight and most places aren’t open when I get off work, and I don’t have time before work to run out to the store. Most craft stores close early on my days off if they are open at all so this is an absolute game changer for me as far as convenience and price. Can order it when I realize I’m running out and it arrives before or shortly after I get off work. Extremely convenient and worth every penny.
