GS Darts UMAΩ Yuma Ike Professional Model I threw it a few times for testing, but I put it away, so it's almost unused. Product Description Yuma Ike's NEW model "UMAΩ" featuring a design inspired by Sado Island. While keeping the overall length of 41mm, which fits comfortably in the hand, the weight has been adjusted from 16.0g to 17.5g. We pursued versatility that is not bound by a specific style, allowing individuality to shine depending on the setup. The main grip has been changed from a ring cut to a double ring cut. Please pick it up and try it. ■Specs Material: Tungsten 90% Length: 41.0mm Max Diameter: 7.2mm Barrel Weight: 17.5g
