I opened it to check the contents, but it has not been used. The color is white. 1. Ceramic inner wall + stainless steel structure with a ceramic finish on the inner wall. With a spacious cup opening and a smooth surface, it is easy to clean, and dirt is less likely to remain, making daily maintenance effortless. 2. Premium stainless steel for 6 hours of long-lasting heat and cold retention. It uses food-grade 18/8 stainless steel and is equipped with double-wall vacuum insulation technology. It keeps hot coffee and tea warm for a long time, and cold juice and iced coffee refreshing for a long time. It is a high-performance insulation design that provides a comfortable drinking experience all season long. 3. 100% BPA-free + ceramic lid for safety and leak-proof design. Made entirely of BPA-free materials, it is odorless and non-toxic, so you can use it with peace of mind. The removable ceramic flip cover is equipped with a silicone ring seal to reliably prevent liquid spills. The straw hole design also allows for the use of a straw. The lid is easy to remove and convenient to clean (capacity 450ML). 4. Welded handle + powder coating for durability and easy grip. The securely fixed welded handle has no risk of falling off and is highly durable. The surface powder coating is resistant to fading, peeling, and cracking, and prevents fingerprints and dirt. It provides a moderate grip for easy handling and an ergonomic design that maintains a dry feel. 5. Versatile use. It is perfect for everyday use at home and in the office, as well as for outdoor scenes such as camping and hiking. It is also ideal as a gift for those you care about, loved ones, and for Christmas, Mother's Day, and Father's Day. Thank you for viewing.
