The Arkiv system is a specially designed, patent pending closure system developed by MISSIONWORKSHOP. Although this system has already appeared in small range of products before, they have announced that Spring 2012 collection will have its own Arkiv Modular Bag System line. This is exciting news as the bag industry is slightly stale at the moment, with no new innovation happening for some time. The MISSIONWORKSHOP crew shot a teaser video whilst setting up their pop-up shop in Berlin, which should give us the taste of what's to come from the new line. Hit after the jump to watch the video in its entirety.
