SPOKANE, Wash. — Dutch Bros Coffee is issuing a “full voluntary recall” of eclipse glasses passed out at their coffee stands.

According to Dutch Bros Facebook, the company purchased eclipse glasses after receiving certification of ISO compliance from the manufacturer but they have reason to question the authenticity of the glasses.

Dutch Bros officials ask people who received any of these eclipse glasses to return them to the Dutch Bros Coffee location where you received them. According to the Facebook post, customers will receive a free drink of their choice if their glasses are returned.
