This is Masahiro Tai's beer glass, model 175. It's a glass that can be used to share a 350ml beer. I used it regularly, though not every day. Approximately φ5cm, H11.5cm * There are some original air bubbles, a few small scratches from use, and water stains overall. * I didn't notice it when I was using it, but one of the glasses has a scratch (thin vertical line in photo 3). * Please be aware that there may be overlooked scratches or stains. If you are concerned about small details or are looking for a perfect item, please refrain from purchasing. I would appreciate it if you could understand that this is a used item stored at home and inspected by an amateur. * Shipping will be done using an empty Riedel glass box. Thank you for your understanding.
