### ⭐⭐⭐⭐⭐ Perfect
*by J***S on March 27, 2022*

This is pure potassium nitrate. Works great for the pyrotechnics that I use it for and for this price is also a steal. I diy with my kids making sugar rockets, gunpowder, and numerous other projects they get off of TKOR on YouTube. So we go through plenty of this very quickly. Will make this my primary supplier from now on.
