SKUs 325-1W, 325-2W, 325-3W, etc. on the horn comb pages – Are they sizes?
The first number (325 in this example) is the comb design.
The second number (1, 2, or 3 in this example) is the thickness of the comb in that design.
The letter on the end (W in this example) stands for the color – this comb design comes in White, as opposed to Ox, which would be B.
