Edco copper foil tape for stained glass, a classic. I've used various tapes, but this is still the easiest to use, No. 1. Even when blackening the solder, the copper-colored backing of regular copper tape doesn't detract from the beauty of the glass, so this color is recommended for all but transparent clear glass. Whether the colored glass is transparent or opaque, the blackness won't bleed from the edges, and the sparkle won't be lost, so please use the copper-colored backing. The width is 5.6mm, which is perfect for 2mm to 4mm glass and is a very easy-to-use regular type. I bought extra when purchasing for my own creations. ● This is not tape that has lost its adhesiveness due to long-term storage, but the latest arrival. ● If you need 2 or more sets, please comment. I will create a page with a 100 yen discount per set. ※ Price negotiations are not possible except for bulk purchases.
