Frequently Asked Questions

Q: What material is the tumbler made of and is it safe for hot and cold drinks?
A: The tumbler is made of high-grade 304 stainless steel with a double-wall vacuum design. This material is food-safe, rust-resistant, and helps maintain the temperature of your beverages. It is suitable for both hot and cold drinks, but please note the tumbler is not microwave or dishwasher safe.

Q: What are the exact dimensions and capacity of the tumbler?
A: The tumbler has a capacity of 20 oz (600 ml). Its size is 2.87 inches (7.3 cm) in diameter and 7.99 inches (20.3 cm) in height. The cylindrical shape provides a 360-degree printable area on the body, and the product has a matte finish with a glossy varnish layer.

Q: Can I customize the tumbler with my own design? Is it suitable for sublimation?
A: Yes, this tumbler is designed as a sublimation blank. The straight skinny shape and matte finish are ideal for sublimation printing, and the varnish layer protects against peeling and color fading. You can apply your own custom design over the entire 360-degree printable area. Note that the product is made on demand with no minimum order quantities.

Q: What accessories are included with the tumbler?
A: Each tumbler comes with a plastic lid and a metal straw. The lid helps prevent spills and maintains temperature, while the metal straw is reusable and fits the tumbler perfectly. They combine to make a complete set for enjoying your drinks.

Q: How should I clean and care for the tumbler?
A: The tumbler is not dishwasher or microwave safe. You should hand-wash it with mild soap and warm water. Avoid using abrasive scrubbers to protect the varnish layer and the design. The lid and straw can also be hand-washed. This care routine will help prolong the life and appearance of the tumbler.

Q: Is the tumbler truly insulated? Will it keep drinks hot or cold for long periods?
A: Yes, the tumbler features double-wall vacuum insulation. This construction creates an airless layer between the walls, which significantly slows heat transfer. Hot drinks stay hot and cold drinks stay cold for several hours, though exact duration depends on initial temperature and environment.

Q: Where is the tumbler sourced from and what is the shipping process?
A: The blank product is sourced from China. Because it is made on demand, there are no minimum order quantities. Shipping times may vary based on production and your location. The tumbler is shipped as a blank (without any custom design unless you order a personalized version). Please check the product listing for specific shipping estimates.

Q: Is there a warranty or guarantee for the tumbler?
A: The product information does not specify a manufacturer warranty. However, because it is made on demand, quality control is typically conducted before shipping. If you receive a defective item, please contact the seller for resolution. We recommend checking the store's return policy for more details.
