There is a set of N.O.S Sanford Penit ink in a local shop and was wondering if it is worth it to pick it up. it includes 2 bottles of washable Royal Blue, 2 bottles of blue black, 2 bottles of jet black copy ink, and then 1 bottle each of Cardinal Red, Green, Violet, Peacock blue, Dubonnet, and brown. The set of 12 is 70 dollars, though they are willing to split it up or come down a little bit as well. I was wondering if anyone had experience with these inks and what they thought of them since I have been unable to find a swab of any of these colors. So do any of you guys have experience with Sanford Penit ink?
