If you’re looking for a cool alternative to your wallet, look no further than 15:21 Cork Credit Card Holder. If you haven’t heard, Portuguese cork is the new leather. It’s soft, feels like suede, and is extremely durable. This means the cardholder will look good for years. It’s also far more compact than a wallet, so it’ll easily fit into your pocket. On top of this, cork is water resistant and buoyant, so if you drop the cardholder into the pool, you needn’t worry. All that said, the best thing this handy little wallet has going for it is its environmental impact, or rather, lack thereof. Cork is 100% biodegradable, and its farming has virtually no negative effect on the ecosystem. 15:21 has created a stylish, durable, and environmentally-friendly way to carry your credit cards.
