[Seamless Design] 20oz seamless silicone sleeve has no seam line, providing a smooth surface for sublimation tumblers, allowing you to apply the image perfectly without wrapping the tumbler with silicone bands. [Heat-Resistant Sleeve] Our silicone sleeve is made of high-quality heat-resistant silicone. It can withstand temperatures up to 482°F (250°C), making full-wrap sublimation printing easier and ensuring it will not melt or stick to your tumbler, protecting your project. [Advantages] Reusable and safe for direct oven use. You can set the appropriate temperature and time for your sublimation needs. The sleeve can be applied and removed quickly and easily without the need for shrink wrap or additional heat. [Easy to Use] Secure the seam, top, and bottom with the included heat tape, then turn the silicone cover over and roll it up from the base of the cup. The cover wraps tightly, applying even pressure to prevent color fading or image blurring at the top and bottom of the cup. [Product Includes] 3 pieces of 20 oz silicone sublimation sleeves, 3 rolls of 30M heat tape for sublimation. Designed for standard 20 oz skinny tumblers to achieve a flawless full-wrap print.
