Coatings by Sandberg dichroic stringers 90 COE. Each stringer measures about 18 inches long. The dichroic coating measures about 2mm wide and runs the length of the stringer with about 1/2 inch uncoated on each end. Packed in tubes of 7 stringer rods in assorted colors and shifts on black.

Tested compatible for great results every time. 90 COE.

Please note: I couldn't get the black stringers to cooperate to get a good photo, so the second photo actually shows the rods on clear substrate. Yours will be on black, but this gives you a better representation than the stock photo.
