Sublimation tumblers are typically made of stainless steel, which is a durable and long-lasting material. The stainless steel is often double-walled, with a vacuum-sealed space in between the walls to provide insulation and prevent condensation. Some sublimation tumblers may also have a powder-coated finish, which can add color and durability to the surface of the tumbler. The lids of sublimation tumblers are typically made of plastic, and may feature a spill-proof design to prevent leaks and spills. Overall, the combination of stainless steel and plastic materials makes sublimation tumblers durable, functional, and convenient for on-the-go use.
