A. These tools are important in the sublimation process and can be helpful for those who want to produce cups without ghosting. Especially when using a sublimation vacuum flask press, this set of tools can be suitable for you. B. Specifically designed for 20 - ounce slender straight - body sublimation vacuum flasks. During the sublimation process, it can 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. C. Compared with plastic silicone clips, the seamless silicone design may not leave gaps and blurry parts on the vacuum flask. D. 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. E. All supplies in the set are made of heat - resistant materials and may not be damaged at high temperatures. The silicone sleeve can be reused. All of these can be useful for the sublimation process and high - temperature projects, making projects better. F. Color: Green + Red G. Material: Silicone H. Package contents: - 2 20 - ounce sublimation silicone sleeves - 2 rolls of blue high - temperature tape I. Only the above package contents are included, and other items are not. J. Note: Light and different displays may cause the color of the item to vary slightly from the actual product. The measurement error can be around +/- 1 - 3 cm.
