I wanted something that I could fit my phone, keys and credit card in - and this was *exactly* the right size. It is made of linen which is nice...silk might not have been so sturdy and washable. I am going to order a few more of these in different colors. Very, very happy with my purchase and Old Shanghai Online :)

Edit: SO BUMMED! Zipper broke 3 months into use, so I didn't bother purchasing any additional bags.
