For those interested in handmade coasters. Those who understand. Approximately 9.5cm to 11.5cm in height Approximately 9.5cm to 11cm in width When you have a cold drink, the outside of the refrigerator is hot, and the glass sweats. I would be happy if you could use these handmade coasters at such times. Since the wet coaster is handmade, I think it will last a long time if you lightly shape it and dry it in the shade.
