1. [Sublimation vacuum flask silicone sleeve set includes] These tools are important in the sublimation process and can be helpful for those looking to produce cups without ghosting. Especially when using a sublimation vacuum flask press, this set of tools could be suitable for you. 2. [Silicone cup sleeve] It is designed for 20 - ounce slender straight - body sublimation vacuum flasks. During the sublimation process, it can wrap and fix the straight - body vacuum flask well, reducing the risk of pattern misalignment and deformation, and making the thermal transfer of the sublimated image smoother and more uniform. 3. [Upgraded design] Compared with plastic silicone clips, the seamless silicone design is less likely to leave gaps and blurry parts on the vacuum flask. 4. [Easy to operate] You simply need to put the sublimation silicone sleeve on a blank vacuum flask with sublimation pattern paper, place it into the vacuum flask press and set the appropriate temperature, and then wear gloves to take out the cup. 5. [Material characteristics] All supplies in the set are made of heat - resistant materials and can withstand high temperatures without damage. The silicone sleeve can be reused. These can be useful for the sublimation process and high - temperature projects, helping to make your projects better. 6. Color: Green + Red 7. Material: Silicone 8.
