The Eco-Leather Tan Purse the perfect grab-and-go accessory for every day. Eco-leather is crafted without using hazardous chemicals in the tanning process. Instead of azo dyes, formaldehyde and other substances, eco-leather is tanned using materials derived from sustainable tea bark extracts and waxes. This "vegetable tanning" was used in India in ancient times to tan leather. From our artisan partner group CRC Exports in India, which helps small, informally organized craft workshops develop into self-sustaining businesses.
