With the Iron Samurai 4 you get one of the most popular midranges on the market, the MD3, for the first time in Discmania's new Chroma plastic. Chroma is reminiscent of the old Luster C-Line plastic and is an extremely durable version of the already strong C-Line plastic with a slightly pearly appearance. Iron Samurai is a signature series for Eagle McMahnon from Discmania's Sky Team and you support Eagle directly when you buy one of his signature discs.
