For precious and more valuable earrings, the Alpa earrings back are made of a spring locking mechanism. Each Alpa back has two small clasps that have to be released once the back has been pushed onto and locked into place on the earring post. The ALPA system is easy to use and is by far the most secure earring back available in this industry.
