Thank you for viewing. This is a set of 2 brand new, unused, durable French plates. "Arcoroc" is fully tempered glass from J.G. Durand & Cie, France. Diameter: Approximately 24.5cm, Height: Approximately 2cm "Arcoroc" has a special surface called "Carapace" (hard shell), and compared to ordinary glass products, it has 2-3 times the strength and can withstand 2-2.5 times the thermal shock, so you can use it directly in the microwave. It's extremely durable, making it convenient for everyday use. I also use them, and they are very useful. Please read the handling instructions before use. Please understand that these are items stored at home. # Please read Nao-chan's profile Please also check out my other products.
