I just started wearing and collecting European bead jewelry, and these earring bases are one of my best foundation pieces.  The finish has the patina of a nice sterling silver.  Since the post that holds the bead simply slides off to mount the bead, then simply slides back on and into its groove, adding a bead is simple.  I won't lose these because the nice lever back keeps these earrings secure.  So far my beads have fit perfectly on the post.  I like this short post that holds one bead because one bead of any material is not too heavy.  Also, if I am putting together a jewelry set, I only need to buy two beads for the earrings. Shipment was timely and included understandable contact information for the seller.  These earring bases came with a lovely little black velveteen storage bag.  Very pleased.
