L-Style is a pioneer in shaping flights that open at 90 degrees, which is the standard today.
Insert the cap-shaped champagne ring into the hole and use it in combination with the L shank. The shape of the cap covers the tip of the shaft to prevent damage from the tip of the shaft. It also prevents the tip of thrown darts from penetrating the tip of the shaft and being flipped during grouping. The edges of the flight are arcuate to prevent it from being knocked off and damaged.
While flight performance remains unchanged, a "flexibility" is added that is sticky and difficult to play. In the event of a subsequent arrow collision, it flexibly absorbs and softens the impact, reducing flight damage. It's high performance flight at a low price.
