I traveled through the Swiss mountains on the Glacier Express. This is a commemorative glass I purchased in the dining car when the train was running on a steep slope. The glass is tilted to match the slope of the track, and the idea is that if you pour a drink into it, it won't spill, which is quite clever. I believe this is a rare item, only available to those who dined in the restaurant car. - Product Name: Leaning Glass - Brand: Glacier Express - Purpose: Souvenir - Design: Leaning glass - Material: Glass Thank you for looking. Diameter: 7.5cm Height: 12.5cm It fits perfectly in a cylindrical tube. It's been stored in the back of a display shelf and is an unused item that I only take out and look at occasionally.
