    Great Lye

    Posted by Danielle on Sep 27th 2020

    I love using this lye and it's fairly priced! It's packaged in a zip tied in a thick/clear plastic bag. Also, the empty containers hold hot lye water solution perfectly! I will keep buying from here!

    Very smooth. Lye retains moisture, but this product was very consistent and dry.
