Our nylon Koi Windsocks are delightful garden ornaments and make a colorful wall display in the home and children's rooms. In Japan, Koi Streamers are traditionally flown on Children's Day on May 5th. The largest black carp streamer represents the Father with the red representing the Mother. The flying koi symbolizes courage and ambition recognizing a tale of a koi that once swam all the way to heaven to become a dragon. Available in Blue, Purple, Red, Black and Green.
