Thank you for viewing. This 400ml tumbler is easy to use with its sliding lid. It's also dishwasher safe, making it easy to clean. I purchased this, but I haven't had a chance to use it due to the capacity, so I'm putting it up for sale. It's new and unused, but please understand that it has been handled by someone once. Please check the photos for details. - Brand: THERMOS - Capacity: 400ml - Structure: Sliding lid - Heat resistance: 140℃ - Dishwasher safe: Yes
