A Bad To The Bone fossil brooch by Erstwilder! This fossilized T-Rex skull is perfect for anyone who loves paleontology and fossils. These little works of art are created with multiple layers of textured resin with hand painted details. The pin comes in a round Erstwilder keepsake box with story card and fossil tag. Erstwilder jewelry is designed in Melbourne, Australia. Story: Millions of years in the making this fearsome fossilized foe is still a tyrant lizard king. Measurements: 2 7/16 inches wide and 1 5/8 inches high. Care per Erstwilder: Please be aware that resin is akin to ceramic and glass and therefore may be damaged if dropped or knocked. Keep your Erstwilder companion neatly tucked away in this box when not being worn, avoid contact with perfumes, lotions, water and excessive sunlight and you'll have a trusted friend for years to come. Due to the handcrafted nature of these designs, slight differences between pieces as well as little imperfections like small specks, air bubbles etc. are to be expected and make each one unique.
