Hello Nancy, Thank you for your interest in our product. This frame is a Mixed-Material made up mostly metal and plastic. It is super thin and lightweight giving the flimsy feeling, most people preferred that for fashion. Check here for more details: https://www.firmoo.com/help-p-144.shtml. Moreover, this pair is one of our hottest styles and we never had any customers coming back with any yellowing. Hope this is helpful. Thank you and stay safe!
