This bag is rather cool, but I'm not sure how practical it would be.
The IHCD store suggests it's sturdier than it looks, but since it comes flat and can be, um, origamied into a bag, I just imagine it might, um, origami itself out again, flinging your groceries or unmentionables all over the street. Still, it's very attractive, particularly the little smiley faces around the edges. By Akanbe, it costs $74.99.
