Well, he is very personable fellow and his grips are quite good.
They are as good as any Faux grips ( polymer ), in or at the same price point...
I have used his grips and they age to somewhat yellowed ...
what they aren't, is real ivory , nor will you pay $800 and be breaking any laws...
Buy with confidence, Gripmaker, aka Larry Little is a stand up guy and well liked on this BB
