Thank you for viewing. This is not stainless steel. Box size: length x width x depth is 14 x 8.6 x 8.6 cm. As shown in photo 6, the box is dirty from transport, but the tumbler inside is clean. The shipping cost is high, so I have set this price. I have other items for sale, and if you wish, I can ship several items together. I often go back to my parents' home to care for my mother, so I apologize, but it may take some time to ship the item.
