Uni Try II Foam Insert

The UNI-Tray II is a light-weight foam insert. Each foam insert holds eighteen (18) spools. To load a spool into the tray, simply remove the tag end of the material from the spool-rim nick and insert the spool in one of the holes leaving a small tag end protruding. Now, exactly the desired amount of material can be pulled from each spool without concern for keeping additional material from falling off the spool.
