Purchased from an antique shop in Japan, but it's been displayed in a cabinet almost unused. The glasses are for 30ml, so they are smaller than wine glasses. They seem suitable for enjoying high-proof alcohol, aperitifs, or after-dinner drinks like wine. If you decant wine, it will be exposed to air, which will enhance its aroma. Decanter height: approximately 23.5cm (approximately 400ml) Glass height: approximately 12cm (approximately 30ml) The craftsmanship is very delicate, but there are some chips on the glasses. Please understand this before purchasing.
