When I went to IKEA yesterday, I saw many molds for baking snacks, which can bake big cakes, and a plate of molds for baking several small cakes, both square and oval, which cost less than RMB 111. There is also Liuliqiao Market in Tongzhou. Go straight ahead from the main entrance, turn right at the last crossing before you reach the end, and there is a very large restaurant selling catering supplies on the left hand side, where there are also various molds, but the quality is not as good as that of IKEA. They are all made of iron.
