There is nothing wrong, the box is very comprehensive and quality. As described, enough to twelve darts, with almost infinite variations, and especially of very good quality every time, quality hair. But do we really need so many heads and wings? All this probably started from an excellent intention, but after several weeks of use, we have never changed once heads or fins. Unless they really wear at exceptional speed which I would not have consciousness, all this seems a bit excessive ... Why not slightly lower the price and halve the number of heads?
