A hand warmer made of Australian Merino lambswool with beautiful color and elasticity. One side has a hole for the thumb to pass through, and the other side has no holes and is a 2-way design that can be worn from either the top or bottom, like the cuff of a sweater. You can enjoy the layered style of the cuffs as if you were wearing them in layers. Unlike gloves, all fingertips are exposed, so you can operate your smartphone or PC while wearing them. By knitting with a WHOLEGARMENT knitting machine that allows for no-sew stitching, there is no cutting process and no unnecessary waste of raw materials. Also, the seam allowance does not touch your skin, making it comfortable to wear.
