Nishiguchi Kutsushita Merino Wool Fingerless Hand Arm Warmers New Arm and hand warmers made of exceptionally fine merino fibers measuring an average of 16? (microns) which is equivalent to that of cashmere. Soft and luxurious, they cover about 3/4 of the forearms (13" long) and most of the fingers, leaving only the tips free for practicality. 100% New Zealand Merino Wool, made in Japan. Made in Japan in a 3rd generation sock factory. Nishigushi Kutsushita (Knitwin Co.) started in 1950, shortly after the war, with one hand-knitting machine. They now have 130 machines in operation and work with a team of craftsmen that ranges from 50 years of experience to younger employees who they hope will lead the company into its future.
