These cat keychain accessories are made with PLA filament, and thus, are plastic and safe to keep on your person as a means of accessorizing, or self defense. We currently have a surplus available, 12 of which have carabiners already attached (this is subject to change as we get more carabiners). Colors are not guaranteed, but I am happy to inform you of if we have a specific color available should you request it. We are also now printing in silk green and silk purple PLA, which leaves a metallic appearance when finished! Please send me a message if interested, I can take cash payments, or payment through Cashapp and/or Venmo!
