This set features 20 oz. sublimation tumblers with a straight, uniform profile designed for consistent heat transfer. Each tumbler uses a double-wall, food-grade stainless steel construction that helps maintain beverage temperatures for extended periods. A dedicated sublimation coating is applied to support direct prints when using a heat press or sublimation oven, producing bright, durable transfers that resist fading with washing. The containers are built to be used as blank canvases for personal designs, logos, or artwork, making them suitable for DIY projects, classroom demonstrations, or small-batch production. The straight shape is achieved through integrated molding technology, which minimizes distortions during the transfer process and simplifies alignment of designs. The set comes with practical accessories to support sublimation work: splash-proof lids, standard sized straws, straw brushes, rubber bottoms, shrink wrap films, and the individual boxes that organize each unit. The 304 stainless steel material meets food safety standards and the design includes insulation to help keep hot beverages hot and cold beverages cool over several hours. Overall, the kit emphasizes uniform dimensions and reliable performance for repeated sublimation tasks across different projects and environments. This arrangement supports straightforward setup, repeatable results, and clear design transfer workflows.
