Bobbin Thread - No Tangle by Bob-EEZ -(2 1/2 DIA 3/4 HOLE)
Allows crafters to spool down & repackage large spools of thread onto smaller, easier to manage spools.
"Has a patented, protective locking feature which prevents threads from unraveling. Stackable and made from soft plastic. Bob-EEZ are also great for macramé! Use multiple bobbins to secure loose ends as you work."
