This is a set of two LIITON rock glasses. I washed them with the intention of using them, but ended up not using them, so I'm selling them. These clear rock glasses feature a mountain-shaped bottom. There appears to be something like air bubbles, possibly from the manufacturing process, but they are not scratches. Please refer to the 8th photo, although it's difficult to see. - Brand: LIITON - Type: Rock Glass - Material: Glass - Design: Mountain-shaped bottom - Quantity: Set of 2 - Transparency: Clear Thank you for looking.
