These real leather keychains make a perfect souvenir for a National park gift shop or souvenir store. The leather is sourced from a leather company out of Ohio and then I add the laser engraved designs to each leather keychain. The keychains are available in 4 colors, take your pick. The size is 2" round. Yellowstone National Park is one of America's favorite parks! The iconic buffalo is depicted along with the words. The keychain is small enough that it won't overtake a key ring or a lot of space in your shop.
