These are heat-resistant glasses from amabro. We are selling a set of two glasses: amber x gray and green x yellow. The retail price was about 5000 yen for the two. * Dishwasher and microwave safe * Do not heat, cook, or dry-burn directly on an open flame, in an oven, etc. Condition: I purchased these in January and have used them three times, but I end up using other glasses more often, so I am selling them. There are no noticeable scratches or stains, but they are used, so I would appreciate it if someone who understands this would purchase them.
