Credit Card Grinder Yin-Yang

This Yin-Yang credit card grinder from V-Syndicate is a unique grinder. Firstly, its compact and flat design allows it to fit into most wallets, making it easy to carry around without requiring additional space. The grinder card features a series of holes in the center, shaped like the well-known Yin-Yang symbol. When you rub your herb over these holes with a top piece, it grinds the herb into small pieces. Once you're finished grinding, you can conveniently store it back in your wallet!
