Agra Grit Walnut Shell Media 18-40 Grit - Medium, Crushed Walnut Shells for Blasting, Polishing, Deburring, Anti-Skid and Fillers, 25 lbs

Used as filler for heating pads. Easy, no odor, worked perfectly.

I like this media. It's the same price as at "the usual suspects" but less of the weight is in dust. Of course it is still dusty, but it is *less* dusty.The scent is quite nice as well, and there was no moisture contamination and the bag was sealed with care.

I like the results. One thing I noticed is the grit is so fine, it tends to put a grain in an unprimed primer pocket. a wooden toothpick or decapping tool works great. That said, next time, I'll order the larger media.

I think i expected too much. But I am not very happy with my adventure into sandblasting. So, maybe I really should not rate this as the things I used it on so far did not work very well. I am sure it works better when used properly and on the correct item. Since I did not have good luck do not let it discourage you. There are loads of folks who use this and like it.

I bought this for filling pin cushions. It keeps pins sharp.
