i know that agnis b bags are very popular in Hong Kong and Tokyo but they dont seem to be popular in North America, but its a French brand anyways i have the black medium size Teflon one (the $1580 HK one), the one with the shoulder straps as well as the detachable messenger strap and its the perfect size for school! it big enough to fit a text book but small enough that its easy to carry around, and because its made of Teflon, its super durable! i bought it last year and have used it ever since for class and it still looks new! the buckles and metal parts look new as well! ohh.. and it has the lock and keys strap, which is neat as well! so my question is what do you think of angis b bags, those of you who have one?
