Item... Barrel Type... Soft Darts Standard... 2BA DYNASTY TRIPLEIGHT effort4 type-B (Effort 4 Type B) Rainbow 2BA Akihiko Yamakoshi Model (Darts Barrel Dart Set) Brand: - I've been throwing it for a few months. The coating is peeling off. There are some scratches, but I think it can still be thrown. The cuts are inferior to new ones, but I think it can still be thrown. ★Product Specifications Material: 90% Tungsten, Single Weight: 20.0g Total Length: 48.0mm, Maximum Diameter: 7.0mm Type: 2BA The 4th "effort" model from Akihiko Yamakoshi is available in two types, "type-A" and "type-B," in pursuit of the ideal. "type-B" is an evolved version of "effort3," which features a 0.2 grip marker. This time, the design has been updated from a triangle cut to a new design with a series of nut cuts. As the rugged look suggests, the grip has been strengthened, and the triangle cut supports the release, creating a new, tried-and-true pattern. The outline, which specializes in rear grip, has a design that expands from the 0.2 grip marker area equipped in the previous model to the maximum diameter, allowing for a smooth transition from "effort3." The micro-rings in the taper area also have a functional design that firmly supports the fingers placed on them.
