The all-metal construction combined with V Syndicate's patented grinder design allows portable grindability that fits easily in your wallet or hand bag. It's the size of a standard business card and each one has its own sleeve cover for protection. With a grinding surface similar to a cheese grater, it can either shred your tobacco finer or be used for various culinary uses such as shaving cinnamon, grating herbs, or slicing a brownie to share! Again, a clever and compact design to always carry and use for a wide variety of purposes. To top it off, these grinder cards are specifically designed to be finger-friendly and easily cleaned.
