This is a set of two beer mugs from Kitaichi Glass in Otaru. I bought them on a trip to Hokkaido 10 years ago. They are what's known as "B-grade" items, meaning the glass clarity is slightly reduced and the shape is a bit irregular, but they have the official logo. (See photo 2.) I think they were about ¥1,200 each. I've used them a few times, but haven't used them at all in the last few years, so I'm selling them. There is no outer box, so I will pack them in a makeshift cardboard box with cushioning. Please note that the third photo is for size comparison only, and a 500ml can of beer is placed there, but it is not included.
