S4Barrel Mirror Finish “Shinuchi” Series!This is the dart barrel series from S4Darts, creators of a wide variety of darts items. What is “Shinuchi”...We've adopted a groundbreaking European mirror finish technology, used even in space development, for processing our dart barrels! The slipperiness that can be a downside of no-groove barrels is countered by precisely mirror-finishing the barrel surface. This provides a sensation of suction when gripped and delivers a secure, slip-free Lilly feel. Experience a barrel finished with a high-quality surface that stands apart from the standard version. <Below: Product description for the Mugetsu Ootachi Ura>A Limited version of the Ura Specifications, pushing the Mugetsu Ootachi to its absolute limits in thinness and weight.

While maintaining the same length, it is 0.2mm thinner and 3.5g heavier. An iconoclastic barrel among iconoclasts is born.
