This isn't really a cheat but try combining a Naolin with another Naolin. This will combine into a Naolin(2). That means it is 2 naolins it one item. It doesn't use them at once and it saves spece. Combine the Naolin(2) with another naolin to make a naolin(3). This also works with Naolin+ and Naolin Gold. I don't know how far you can go but it helps.
