This is a collaboration glass between McDonald's and Coca-Cola. The colors are blue and green, and the text on it says: crown glass 2013 So I believe it's a commemorative item from 2013. It's new and unused, but has been stored in a cupboard for a long time. Please wash it carefully before using. Each glass will be carefully wrapped in air cap (bubble wrap) and shipped via the "Rakuraku Mercari Bin" home delivery service. Thank you.
