Set of 6 rock glasses I believe these are HOYA products, but I apologize if I'm mistaken. These have been stored in a cupboard with minimal use. I believe they are in beautiful condition. These are not delicate glasses; they have a solid, weighty feel. Each glass weighs between 350g and 370g, with some individual variation. The tray used as a background in the photos is not included. There is no box. They will be carefully packaged and shipped via Mercari's anonymous delivery service.
