An anti-oxidation protective film is formed,extending the natural function of feather,decreasing the injury of the bone and thus improve the durability. Two-times Gluing Helps Under the work of two-times gluing with Repairing Liquid & Nano Glue,feather's density is increased,toughness is strengthened,the maximal rebound angle for the feather can reach 45º.
