BUDAPEST—While audiophiles might argue that their favorite recordings sound best on vinyl, there are still enough old unwanted albums that a company called Vinylize is turning them into sunwear.

They even turn discarded 7-inch singles into cases for those recycled sunglasses by folding them in half and sewing on a zipper. This video shows how they are “Handmade in Hungary.”
