These previously unwanted lumbers are detoured from landfills and repurposed into cleaning tools by our partner artisan in Central Java. gt; Coconut husk - the bristles of our tools are made out of coconut husks (natural fiber extracted from the outer husk of coconuts). Coconut fibers are resistant to grease and they naturally inhibit bacteria growth. Did you know Indonesia is the largest coconut producer in the world? Talk about renewable! Storage amp; Care: Do not leave brushes soaking in water as the wood will absorb it - this may cause swelling, cracking, or the natural bristles to fall out prematurely. Hang to dry in between uses, on a dry towel or elevated to allow bristles to drain. Wood is naturally antimicrobial, but when you need to clean your brushes, use vinegar to kill bacteria.
