Straw-type spout makes it easy for kids to drink. The edge of the spout is rounded so it feels comfortable on the mouth. You can also detach the straw inside to drink. The back of the lid is flat, so drinks come out smoothly until the last sip.

Care: Be careful with infants as their mischiefs may cause accidental ingestion or injury. Close the lid tightly to prevent spills or leakage when carrying. Please attach silicone rings so that the right side is up. Immediately wash and dry well after use, then store it away from other metals to prevent rust. Do not leave it soaked as it may rust or break. Wash with care. Do not use abrasive cleansers or steel wool. When rust spots are found inside the tumbler, add warm water and citric acid in ratio of 10:1, wash with soft sponge after leaving it for 2-3 hours, and rinse well.
