Got them a long while ago, back when I was considering making circuit boards via old-school resist-and-etching for a simple load cell amplifier. Two sheets have remnants of attempts at ironing laser printer output as resist material onto the copper. Had some success but not enough to continue. Anyway, those remnants will come off with fine sandpaper or steel wool.
Free, I pay postage. Would prefer that they go to someone(s) with a specific use in mind rather than just leaving them on a shelf (like I did
) until a use turns up. Regardless... they'll go to someone.
