One of the great things about markets in Asia is that they have everything. It is better than going to the mall because you'll get better prices, and if they don't have what you want they know where to get it. Sometimes all you need to do is ask and they can procure it while you finish the rest of your shopping. The people who have stalls are like retail wizards conjuring the most unlikely things from their stacks of stock. Here you can buy tools of all sorts along with fasteners galore and a variety of other random useful things.
