Take a dive into borax with us, first found in dry lake beds of Tibet, but came to fame by American miners *cough white dudes cough* who traipsed  into Timbisha Lands (what is mostly referred to as Death Valley) and started hauling borax out of the valley via the 20 mule rule, this is still a brand name so lets not buy that brand anymore, refill with us, okay?

As for uses, Google that along with reading the story of How the Timbisha Shosone got their land back

At this time you will receive your dry goods in compostable bio PLA lined Kraft paper tin tye bag. If you do not have the means to compost bring them back and we will do it for you.
