Sterling Silver Tapered Bar Crawler Post Earrings You might be asking, "What is a crawler earring?" And here's your answer: A crawler earring can be rotated to extend up your ear instead of hanging down from your piercing. Created an edgy look. What we love about the crawler is they look great worn up or down. These are slightly curved and tapered spikes, about 14mm long. Sterling silver earrings, posts and backs. All of our jewelry comes boxed and ribboned, ready for giving (or keeping)!
