Solder purchased about 8 years ago for stained glass making. Unused and unopened, it has been stored in the original bag from when it was purchased. I am selling it now to organize my belongings. The purity details are unknown (as I have lost the documents), but I believe it can be used without any problems as an unused item. ● Contents Approximately 250g and approximately 230g per roll (approximately 480g total) Please check the width and length in the photos. Purity details are unknown. I will sell it to those who understand that it has been stored for a long time. I will pack it carefully and ship it. I am open to price negotiations. Thank you for looking.
