Starbucks PORTER Stainless Steel Bottle Matte Black 591ml New, unused. No box. Selling because I didn't use the 591ml size. Thank you. The following is quoted from the official website: Collaboration item between PORTER and Starbucks. The PORTER box logo is designed on the front of the bottle. The embossed Siren is on the back of the bottle. The matte body with powder coating and the contrast of the gloss of laser etching create a beautiful and chic design. The hidden pocket of the helmet bag, which is sold at the same time as the bottle, is designed to fit this 591ml size bottle. Also, the color scheme is arranged to match well with any combination. It has excellent heat retention and cold retention with a vacuum double-walled stainless steel structure.
