Can't find this stuff just anywhere. I have approx. 145ft of 0.8mm diameter, 90% tin/10% silver solder for sale. I'm not gonna sell all of the spool (which is more than 145ft), since I'll be using some of it. $3.99 for 1 foot, shipped to the USA. $3.49 for each additional foot. Paypal, check, or MO. Shipping is plain ol' snail mail. Priority mail or any other shipping is on the buyer.
