While wholesale-only here, if interested in buying just a stone or three here are online and physical store outlets carrying Mt. Shasta pumice. Most offer stones in bulk (not packaged). Some onliners have storefronts as well, and imagine some storefronts also sell online.
Best online deals indicated. Click name to visit any site. Directions for finding stones on sites sometimes indicated, as they're sometimes hidden among mountains of exotic artisan soaps, lotions and such. Some links open directly to pumice offering.
