An environmentally friendly bio-compostable plastic made from corn starch, it is a versatile & easy to print material with high rigidity with excellent surface detail & a high gloss finish. The reel contains 1kg of filament so Approx. 335 meters in length, & as a rough guide, 5 meters of filament would offer around 30 minutes of continuous drawing with the Polaroid Play Pen, so would last around over 30 hours of non-stop glowing creations! Not just for Polaroid products, this filament can be used in many 3D printers & pens that require 1.75mm diameter PLA filament.
