I bought this cheap EVA foam pack off Amazon for my Mandalorian armor build back in July. It was like $60 for a bundle of 10 sheets, which seemed like a steal compared to the name brand stuff. First cut I made with my box cutter, the edge just disintegrated into this ugly powdery mess. I tried heat sealing with my heat gun, and the whole sheet bubbled up and got this weird texture like orange peel. After three tries I realized the foam density was way too low, maybe like 2mm or something useless. I threw the whole stack in the trash and ordered CosplayFoam brand instead, which actually worked perfect. Has anyone else fallen for those cheap multi-pack foams that look good in the listing photo but are basically trash?
