Runner bags are yellow, multi-pocketed bags used to carry items and/or documents during a Runner's run across the City of Glass, built to be durable to keep the items safe during transportation. It should be noted that Runner bags are not the only form of containers Runners use to transport items. Smaller, yellow cylinders have also been used most probably for smaller, lighter materials. A bag's drop point is marked by a Runner's symbol or tag; in Faith Connors’s case, however, bag drop points are marked by red Runner glyphs (the "Mirror's Edge" series logo).
