This simple and supple leather cardholder in black features three card inserts. 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.
