EVA foam

EVA is one of the most important materials out there to all levels of cosplayers. It is a strong, flexible, formable and cheap material. It can be used for nearly everything cosplay from armors to props. Its main use is for metal or composite replication, meaning armor and all kinds of it! If painted properly the foam can look just like metal or composite materials like Iron Man Armor, Mass Effect Armor or even Dragon Age Armor.
