This is a popular Starbucks Sakura Series water bottle. It's a small bottle, perfect for carrying around, and holds one serving of Starbucks VIA (about 180ml). Its slim shape makes it easy to hold, even for those with small hands, and it fits easily into small bags. It has a vacuum-insulated stainless steel construction, providing excellent heat and cold retention. Size: 4.6cm x 16.7cm I planned to use it, but I bought an electric kettle at work, so it's been stored in the cupboard... It's unused. I hope to sell it to someone who will cherish it, not resell it. Please contact me if you have any questions! Thank you.
