Manja (or manjha), is the abrasive string used with fighter kites in Afghanistan, Bangladesh, Chile, India, Nepal and Pakistan. It is gummed, coloured and coated with powdered glass.
Kites are fought all throughout the year and during special kite flying festivals in the region. Two fighters will entangle the glass powder coated manja while flying their kites in the sky and try to cut off the string of each others kites
