The green hand pads are identical to the maroon hand pads but they are safe to eat. Selling to dairy companies you have to sell the green, but grit wise they are medium just like the maroon. In the roloc discs the blue to me is green. It looks green to me anyway and that is why I always say greenish blue. I will copy the chart and post it soon.
