Ideal for team or school practice, addressing concerns like "intense fatigue during team practice" and "high costs associated with middle and high school club activities." This shuttlecock utilizes the thick, heavy base of feathers that were previously discarded, which are not used in the conventional 16-feather design, making it environmentally and budget-friendly. It receives high praise for its flight performance during clear shots and durability during smashes, especially for a low-cost practice shuttlecock.
