The bags are back!

Each year, Warner Bros. provides bags to every San Diego Comic Con attendee upon onsite check-in, and this year is no different. Remember that new this year, you’ll be picking these up in Sails Pavilion, along with your lanyard, program, and more.

This year’s bags will feature 18 different designs, including The 100, Arrow, The Big Bang Theory,Blindspot, DC’s Legends of Tomorrow, The Flash, Gotham, iZOMBIE, Lucifer, Supergirl, Supernatural and a combo bag with The Originals and The Vampire Diaries, as well as Warner Bros. Animation series Justice League Action and Teen Titans Go! Two bags will also feature upcoming films Suicide Squad and Fantastic Beasts and Where to Find Them from Warner Bros. Pictures.

New this year, the bags come with a hidden secret — an interactive, augmented reality experience courtesy of the visual discovery app Blippar.
