This is an exact copy of the My Everything Stick weaving tool miniaturized and made into a cute little necklace. This is actually a working My Everything Stick and the bobbin is removable. Whether you'd ever use it or just wear it is anyone's guess. :)
This little shuttle is approx. 4" long x .80" wide. 
Choose between a 16" 1.5 mm or a 24" 2.4 mm Stainless Steel Ball Chain.
These would make an amazing Stocking stuffer for your favorite weaver.
