it's 30mm, and 2.5mm thick. This sucker can take a beating! Material is Polykarbonat, for ductility. (http://www.cdplast.dk/ Danish site, I had to go there in person) It's 1000mm long, or 1 meter for non-engineers. (3 feet and a quarter, for americans)

The white stuff you see is some sort of wrap the store used for shipping their items. it resembles foam-wrap, that is unfortunately the best description I can give of it. EDIT: A kind Redditor, jaywil85051, sent a link to what it is: http://www.starboxes.com/foam-wrap-11612.html?gclid=CInjz-2Cv7oCFQ2g4AodLB8AMQ

When fighting strangers, the foam also functions as a shock absorber.
