Mugetsu Ootachi Releases S4Barrel's Highest-Grade Specifications “black Shinuchi” ver.This tungsten dart from S4 (S4) features a wide variety of darts goods, ranging from unconventional forms to super practical darts. An industry first! This ultra-premium model employs triple-processed black Shinuchi. What is “Black Shinuchi”?It involves triple processing: mirror polishing + coating + mirror finish. First, it undergoes mirror polishing identical to the Shinuchi. Next, it receives a purple-black coating treatment. Finally, a second mirror polish is applied over the coating, carefully performed to prevent the coating from peeling. The result is a coating barrel with an unparalleled, vividly lustrous mirror finish. Its grip offers a unique feel distinct from the Shinuchi or standard coated barrels. Experience a barrel finished to a quality surpassing even the Shinuchi. While coatings typically fade and peel over time with use, the Kuro Shinuchi features a mirror-finished tungsten surface beneath the coating. This allows you to enjoy the barrel's aging process as it develops character with prolonged use.<Below is the product description for the Mugetsu Ootachi Ura> A Limited version of the “Mutsuki Oodachi” refined to the absolute limits of thinness and weight.
