We developed a great way to distribute cost effective quantities of flexible filament: Splash Spools. A generous amount of filament on a spool with a case so it's not flopping all over the place. Splash Spools store easily in a desk drawer, stacked space or even hang on a wall. Available on www.flexyfilament.com and Amazon. We stock NinjaFlex, Cheetah, X60, Filaflex, nGen FLEX and Flexy.
