These are Okinawan glass products purchased in the 1970s. They have been stored in a cupboard and have hardly been used. I was told they were made by recycling glass from beer bottles. They are amber-colored and have air bubbles, and the uneven shapes of each glass give them a handmade warmth. One of the five glasses has an irregular shape at the rim, but it does not affect the mouthfeel or use. Please check the last image. Size: Mouth diameter: approx. 7cm Height: approx. 15cm Capacity: approx. 250ml Weight: approx. 300g ⭐️Price reduced Please understand that these have been stored at home. When shipping, we may use recycled packaging materials, so please be aware of this.
