Our ZOO BISCUIT key chains are too cute for words. The Collection consists out of 6 Key Rings (Africa, Lion, Leopard, Elephant, Rhino and Buffalo). This is a great gift for any South African. We love ZOO BISCUITS & this will definitely bring a smile to many faces. Dimensions (60mm x 41mm x 9mm). They are 3D printed using Polylactic acid, also known as PLA. This is a thermoplastic monomer derived from renewable, organic sources such as corn starch or sugar cane.
