These are so cool!! Honor the nature worshiper and the punk rocker inside you. These necklaces are made from Turkish brass and are 16" in length on micro ball chains with lobster clasps. The Gold Raptor skull is just a bit longer at 17" in length. The The Long Beak bird skulls are 1 1/4", the Fruit Bat is a bit over 3/4th", and the Gold Raptor is about 1" in length.
