I received this as a prize from a bayfm radio program. I have kept it stored at home for a long time without ever using it. It's a valuable item with a handwritten signature from the DJ. I think the capacity is about 350ml, but I'm not sure because there were no detailed instructions included. 【Size】 Height: Approximately 15cm (with lid) / Approximately 11.5cm (without lid) Diameter: Approximately 6.5cm Although it is unused, please understand that it has been stored at home. #bayfm #dj Mappy #dj Mappy #Tomoko Matsumoto #Signed #Not for sale #Stainless steel bottle #Carabiner Type...Other Material...Stainless steel Target...Unisex
