biokite hayabusa
It is called biokite but actually just a kite made into a shape of bird. There are a variety of biokites available, such as condor, falcon (hayabusa), seagull, or even butterflies. I tried flying the kite today, but it was very frustrating as the wind stopped so often. On the contrary, when the wind was too strong, the kite flipped upside down and hit the ground. Thought it was quite difficult to handle. I also felt the string was super thin and hard to find when I had to rewind it.
