Found while cleaning out a closet corner. Never-used Kaiser retouching colors for black-and-white. They're similar to those watercolor paint sets you used as a kid, but much fancier and including German instructions. Each of the little color tubs is about the diameter of a US quarter, and much thicker, so one set will last a lifetime. I'm still using a set of nearly full Spotone bottles so I'm not really sure why I bought these. I believe they're now discontinued. $10 plus shipping. Sadly, shipment to any non-US destination will be silly-expensive, but I'm game if you are.
