The horse tail hair we buy comes from the area that comprises northeastern China including inner Mongolia and Mongolia. The hair must be cleaned with a mild detergent (no bleach), rinsed and dried in a cool dark warehouse for several days, turned carefully and by hand. The hair should be quickly sorted and combed (with hackles), tied off in a bundle. The hair should be drawn, butted off and tied into loose bundles weighing no more than 500g, and wrapped in opaque paper for shipment. We purchase bundles in 83cm lengths. The hair is brown, silver-grey, white (unbleached), black and mixed. We prefer to work with dealers with 20 years or more experience purchasing tails, preparing the hair and selecting only the best hair strands for our market.
