Any insulator from Koransha is extremely scarce to locate and get from Japan, especially with colored glazing. During my trip to Japan, the only Koranshas I saw were either all white or white with the orange band and even getting those are near impossible unless you have contacts. This small pintype is a light cobalt blue glaze with Koran ink stamp underglaze and is VVNM condition. Insulator is quite old and not dated. No chips, cracks or breaks and glaze has very minor, light dullness because of age but is still in excellent condition. Shown with a CD 106 for size comparison. Please note that these insulators are VERY hard to get and will not be going on sale. It took me 4 years to locate these and the 1 for my collection. $95 shipped USA/CANADA.Other countries I'll equally assist with shipping.
