Blue dragonhide

Blue dragonhide (also called Blue d'hide by tanners) is an item that is a 100% drop from blue dragons when they die. Players can take it to a tanner to turn it into blue dragon leather for a fee of 20 coins, 45 coins from Sbott in Canifis. Tanners can be found in Al Kharid, the Ranging Guild, Varrock, Taverley, Canifis, Prifddinas, and the Crafting Guild.

Members can then make blue dragonhide armour from blue dragon leather via the Crafting skill if they have a high enough level.
