Purchased several years ago and used for about 3 years. Capacity is 370ml, and it can keep drinks hot or cold. It can be used for direct drinking or with a cup. Since it was used by a child, there are quite a few scratches and signs of use. It can still be used, but I think it would be best for parts replacement, etc. There is no box or instruction manual. *Please refrain from purchasing if you are sensitive to used items, as this item has been stored at home and is a used item.
