This keychain is recommended for those who own Shih Tzus or Maltese! You can put a ball of your beloved dog's fur inside, and the keychain will be colored by the fur. It's an item you can attach to your bag and carry with you at all times. I thought it would be cute for families to have matching ones, so I made it a set of two. ⚫️This is an overseas product.⚫️
