PLC filament for a 3D pen is popular for making jewellery and decorations. It has a melting point of 68°C, lower than ABS filament, and the resulting product is also somewhat more flexible than items made from ABS filament. The material this type of refill is made from is biodegradable. The pack contains 10 differently coloured refills - white, yellow, beige, pink, orange, red, green, blue, grey and black, each 5 m long.
