National Souvenir Center
While the items here may not be as unique compared with Insadong's other shops, the National Souvenir Center is a good one-stop solution. Here you'll find a number of shops, each focusing on a traditional type of craft; the items are all authentic and (generally) of high quality. There are ceramics, jewelry, textiles, art, and—if you must—an "I Love Korea" t-shirt.
