It has been in my house for 50 years. It was collected by my mother, who loves antiques. It is extremely thin. It is thin but sturdy. I would love to know what kind of craftsman made it. Nowadays, we see things made of "Shotoku Glass," but is this a precursor to that? It was used about twice for New Year's. My mother originally bought it at an antique shop, so it is not unused. For those who like antiques, old items, antiques, and vintage items. The presence of air bubbles also indicates its age. There is etching (though it's hard to see...) of flowers and grass. There are water marks, but no chips or cracks. It has a deep, rich character. I don't want to part with it, but my room is too cluttered, so I am letting go of this wonderful tokkuri. I think it would also be nice to put wine in it. Height: 17 cm Mouth diameter: 4 cm Capacity: 380 ml Please excuse any errors. Thin-walled glass Sake vessel Showa retro Taisho Roman
