These are ISO rated solar eclipse glasses. Be prepared for the solar eclipse next April. We do not want to have to get into mailing glasses to deliver them. What we plan to do is have them available at upcoming LAS public & member events such as the Parklands event on Jan 19. We are selling them on-line in advance to minimize cash handling at these events. Once you purchase glasses you shall be emailed a receipt. Bring that to receive your glasses.
