This is the authentic manchu style thumb ring based on actual antique military thumb rings used in the Qing dynasty. Ideal for manchu bows, and other long draw length bows. 
 
Material is the thick plate part of the moose antler. This part has the blood vessel belt, making the ring more comfortable to wear. 
 
*IMPORTANT*  Fitting can be tricky! 
 
Must use a caliper to take accurate measurement. Please refer to this page to measure.
 
NOTICE: Due to limited supply of good moose antlers, the production of this particular kind of ring can take more time than usual.
