The Katseye custom tumbler is a stainless steel drinkware option available in 30 oz and 40 oz sizes, designed for everyday use and fandom style with vintage-style girl group and Kpop group prints. The 30 oz model lists Cold 24 Hours among its features and includes a reusable straw and lid; the 40 oz model is made from high-grade stainless steel with double-walled, vacuum insulation and a spill-resistant rotating lid that offers straw or standard openings.
Both sizes are built for temperature retention and practical daily use. The 40 oz tumbler supports permanent laser engraving customization, while the 30 oz offers reliable cold retention. Handles provide a secure grip, and multiple handle color options are available.
Care is straightforward: these tumblers are dishwasher safe (not microwave safe). They suit commuters, concert-goers, collectors, and anyone who wants a large, insulated cup with a printed design and convenient carry handle.
