If the Merrimint balm melts, cools, melts again (etc) it can start to take on a gritty texture. This is because of the natural melting point of the clean ingredients inside. If you have just purchased a Merrimint and it feels "gritty," please reach out to us at sayhi@jihi.com and we will replace your jar. To prevent grittiness from developing, store in a cool dark place.
