High Quality product!

This is the best deal I have seen on lye. It lasts a while. I use it to make our tallow soap/shampoo bars and I can get several recipes out of one container. It does not smell. You definitely need to be careful when using and make sure to use skin and eye protection. It dissolves easily and does exactly what I need for it to do. This is the only brand I buy for our soap.
