Anun Membrane Gloves are a great pair of gloves for Bureaucrats and Traders. As you may have guessed from the name, you're going to have to find some Anuns. They will occassionally drop an Anun Wing. This may drop in various QLs, and will be turned into gloves of the same QL. Do note that the gloves have the same requirements and provide the same buffs at lower QLs. Since the gloves are NODROP, you're going to have to build them yourself, and the higher QL the Anun Wing, the more skill that requires. So you may want to look for a low QL one.
Anuns may be found in Avalon, Perpetual Wastelands, Mort and in missions.
