12,000 Grit Aluminum Oxide Rock Polish Powder, 2lb Extreme Fine Final Stage Rock Tumbler Polish, Stone Polishing Compound for Rotary & Vibratory Tumblers, Lapidary Finish

I use an eBay seller called craftanddesignuk for my silicon carbide grit, which are a little cheaper than the fossil shops online. For polish though I have to buy it from the USA. I bought the 1200 AO powder from that eBay seller and the stones just didn't shine up enough. I buy the 12k on Amazon it arrived fast and there was no duty etc added on. Only had to buy one bag so far since November and I still have most of it left it will last ages (I use 2 1.5lb barrels). It was way cheaper on Amazon then buying the12k from polished rockshttps://www.amazon.co.uk/gp/aw/d/B0D4PSKZRH?psc=1&ref=ppx_pop_mob_b_asin_title
