Good for beginners
Color: Blue
The gloves are not the greatest, the ones I received with my tumbler press are definitely nicer quality. The tape dispenser is constantly coming apart which is an easy fix but does get annoying at times. Overall it’s a cheap set of items that help with various sublimation items. Based on what you pay vs what you get, it’s worth it.

Everything You Need for Sublimation
Color: Pink
This kit has all the tools I need for sublimation projects. The rulers, Teflon sheets, gloves, and tape make the process easy and safe. Great for beginners or pros.

Craft Room Staple
Model: Kraft er Paper 002
I purchased this butcher paper for my craft room, and it has been a fantastic addition to my supplies! I primarily use it with my heat press, and it works perfectly to protect both my designs and my press during sublimation and other heat-transfer projects. The paper provides a great barrier and prevents any ink bleed-through, keeping everything clean and professional-looking.
What I love about this butcher paper is its versatility. Beyond the heat press, it’s handy for a variety of other craft projects, like covering work surfaces for painting, wrapping delicate items, or even sketching out design ideas. The roll size is generous, so it lasts a long time, even with frequent use.
The quality is excellent—it’s thick enough to withstand heat and pressure but still easy to cut and handle. It’s a must-have for any serious crafter or DIY enthusiast!
