If you want the best value possible considering the amount of variable sized rock, This may be for you. This is about 15 pounds of Premium Georgetown flint spalls and flakes about 50/50% mixed, all crammed into 1 Medium Flat Rate Priority box. This is a good mix of all sizes and will keep you in points and knife blades for quite some time. This Flint is what I consider to be among the best of the best in the country and I am thrilled to now only have enough supply to use, but also to offer my customers. You will definitely find cheaper rock, but you will not find better. shipping to the USA is included in the price.
