Vial cap single small or large stud earring pair or small dangly earring pair! Small vial caps (numbered) available in dangly or stud, large vial caps (alphabetical) available in stud form only. Can mix & match colors for stud or dangly if want unmatched color set. Vial caps originally serve a purpose in medicine as a sterile dust cap that covers unopened vials of medication. Vial caps typically are removed & tossed once a medication is opened. Instead of tossing them, I began saving them for repurposing! Each vial cap ring showcases a vial cap that once adorned a real hospital medication. First they got to protect medicines to help patients feel better, & now they get exciting new life by being repurposed into colorful, wearable, & durable jewelry! Listing is for one pair of earrings with earring backs included. Vial Cap Earrings, Single Small/Large Stud Or Small Dangly
