This package contains two Spider Thread spoolers, each with over 25 feet  of ultimate super-fine invisible thread, designed specially for the  Spider Pen, Tarantula, and other motorized reels in the Yigal Mesika  series. 
 
Intended for the use of levitating and animating objects!
 
As this is a refill, we supply just the spool and not also the reels with wich they should be used.
