These are Flexocors. AKA "new" Flexocors. "Flexocor 92s" etc. Not to be confused with Original Flexocors. A great arco string. Plenty of life left in them. The winding on the D separated just below the top silks. I think I might have kinked it on accident. Anyway, I don't want to sell it. $40 for the three shipped anywhere in the U.S. Paypal is fine, and in fact, preferred. E-mail will be faster than an IM.
