Stained Glass Solder Sticks (25 pcs) & Copper Foil Tape 7/32" (5.6mm) Black Back

?This is a set of 25 solder sticks and copper tape, purchased from a craft store over 10 years ago.
?The copper tape has been opened and partially used, but I believe there is still over 80% remaining. The back is black, and I tested its adhesion by applying it to a glass scrap; while subjective, I believe the stickiness is normal.
?The solder sticks are 3mm in diameter, approximately 395mm long, and weigh about 25g each, for a total of 625g for 25 sticks.
I no longer have the documentation for the tin content ratio, but I calculated the weight by determining the volume of one solder stick (photos 10, 11) and multiplying it by the specific gravity of 60% tin/40% lead solder (around 8.93) and 50% tin/50% lead solder (around 9.34). Calculating the volume for a 3mm diameter, 396mm long stick and multiplying by each specific gravity yields 25.0g and 26.1g, respectively. Since one solder stick weighs 24.9g, I believe this is approximately 60% tin solder.
?The items themselves have no noticeable dirt or damage, but since the copper tape has been opened and used, I have categorized the item as slightly scratched or dirty. Please consider that there may be signs of age, and I ask for your understanding. Thank you.
?Shipping will be via Yu-Packet Post.
