This is a 355ml plastic tumbler from Starbucks. Capacity: 355ml Color: Green/White Material: Plastic Type: Tumbler I've used it a few times, but I'm selling it because I've started using something else. You can get a few yen off your purchase if you bring it to Starbucks, and it's also eco-friendly. Due to its size, the price includes fees, but I'm open to negotiation. Please comment if interested.
