PLA FILAMENT SILK MULTICOLOR - Fast 5 colors change with blue, green, yellow, pink and purple, so you can get all colors in one object-about 200g. The color transition is natural and beautiful and the silk filament has excellent gloss.; SMOOTHLY PRINTING - With greater toughness, 3d printer filament feeding will be smoother and will not break in the tube. The dimensional accuracy of the Rainbow PLA filament 1.75 mm is +/- 0.02 mm, so that print will be smoother without jamming nozzles.
