1. [Sublimation vacuum flask silicone sleeve set includes] These tools are essential in the sublimation process and are very helpful for those who want to produce perfect cups without ghosting. Especially when using a sublimation vacuum flask press, this set of tools is perfect for you. 2. [Silicone cup sleeve] Specifically designed for 20-ounce slender straight-body sublimation vacuum flasks. During the sublimation process, it can perfectly wrap and fix the straight-body vacuum flask, preventing 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 will not leave gaps and blurry parts on the vacuum flask. 4. [Easy to operate] You just need to put the sublimation silicone sleeve on a blank vacuum flask with sublimation pattern paper, put it into the vacuum flask press and set the corresponding temperature, and then wear gloves to take out the cup directly. 5. [Material characteristics] All supplies in the set are made of high heat-resistant materials and will not be damaged at high temperatures. The silicone sleeve can be reused. All of these are good helpers for the sublimation process and any high-temperature projects, making your projects more perfect. 6. Color: Green + Red 7. Material: Silicone 8.
