The Humble Tounge Cleaner - One of our newer additions to the Humble Family! Tongue scraping is a fast way to remove extra particles - including the ones that cause bad breath - from the surface of your tongue. The Humble Tounge Cleaner has a handle made from 100% biodegradable, sustainably-grown bamboo. The bristles are made of nylon-6 bristles from Dupont. The packaging is eco-friendly, the box and inside wrapper are made from recycled materials, and can be thrown out with the organic trash.
