Dragon nails are the best type of nails in RuneScape. When used in construction they will never bend at all. These nails can be obtained in a few different ways. One is to buy them at the Zanaris marketplace for 2,000 coins each. A second way is a reward from Treasure Trails or random events. They can also be found as drops from the Skeletal warrior, which has many other Construction related drops. These nails are also used in making dragon brutal arrows.
