If you already get your sub paper tight I wouldn't recommend it. I had trouble keeping my wrap tight to tape and this works great.

These clamp clips will hold the tumbler securely and can be easily adjusted and removed. It makes applying tape easy. I purchased another set for a friend who has the same crafting hobby as I do.

I have been doing sublimation tumblers for two years. While I have learned a lot of different techniques and ways to improve making my tumblers, there were still times I would get a bit of ghosting despite my efforts to wrap the paper tight.
I've tried multiple things to make the paper tighter on my own. This tool is a game changer and is super easy to use to achieve the results you want.

Herramienta de gran ayuda para una excelente sublimación!
