Our pumice is a natural volcanic product mined in the Southern Cascades Mountains of Oregon. You get only clean pumice... no rocks, roots or other debris.
Known as the "rock that floats", pumice has many tiny gaps or air pockets.
15 oz packages of pumice are sent first class, all other quantities of pumice are shipped Priority Mail. Our pumice is hand packed and bagged with a reusable tie for easy storage after you have used part of the bag. If your pumice dries before using, moisten it to keep dust from forming. Dust from any rock or potting soil product should not be inhaled and can be irritating for people with sensitive lungs.
Pumice can not be combined with other items for combined shipping.
