Review on SUNLU PLA 3D Pen Filament Refills - 10 Bright Rainbow Colors, 164 Feet Total (50 Meters), 16.4 Feet Per Color (5 Meters), 1.75Mm For Most 3D Doodler Pens, Easy To Use & High Compatibility by Jared Peck

This was used to print a snake hide based on a feature in a video game. I’d mistakenly used a smaller volume than needed and was forced to change colors mid print. Both of these colors are Sunlu filament and I couldn’t be more pleased with the result. Looking at the picture of the support material, you can see they blend flawlessly, as though it all came from one spool. The wood color is very subdued and quite natural in appearance and the blue is vibrant. Probably, the best mistake I’ve ever made 3D printing. I was so impressed by the wood appearance, I bought another spool just because.
