This is a Umeboshi Denka cup. Approximately 5.5 cm in diameter, 9 cm in height. There is no print fading, but there is some slight discoloration and fading. On the bottom, there is a mark that I believe is from Sasaki Glass. It was difficult to photograph, but it looks like the mark was stamped twice, perhaps misaligned? I think this is a rare item, so how about it for those who collect these? Please purchase only if you understand that this is an old item. I have various other items for sale as well. Please take a look! I welcome combined purchases♪ #nittanretro #nittanlistings #ShowaRetro #AntiqueMarket #FleaMarket #Collection #Era #Antique #Vintage #CharacterGoods #FujikoFujio #UmeboshiDenka #Cup #Glass
