The Japanese clothing manufacturer 'Animation Addict Store's "You're Such a Nerd" brand has now started accepting pre-orders for bags that have been created with inspiration from the cardboard robot suit in Yotsuba&!. The bags that are to be sold include a tote bag, pouch, and a "carton bag" that is designed to fit Yotsuba&! graphic novels. The range of bags are to be made of a special type of paper in Japan called "Naoron", which is very water-resistant and durable. The carton bag and the tote bag will both sell for 5,250 Yen and the pouch will cost 2,940 Yen, with pre-orders being accepted until June 28th 2013.
