Portable Design: Can be set up either horizontally or vertically! Better shaped, much lighter than other swift. With anti-slip gaskets can be kept mounted and fixed on a table easily. DIMENSIONS: 17.1 x 19.1 x 20.9 inches, clamp/clip height 1.69inch (4.3cm), which holds the swift in place and spins freely as you wind skeins. Easy Use: just turn the crank of the knitting winder to turn the loose skein into ball of yarn, and wind up to 4 ounces of yarn each time; If the skein is pulled out directly from the ball state, it can prevent tangling.
