  • Cute rainbow
Color: Pla Rainbow 01 Material Type: PLA Rainbow Filament
Very subtle rainbow with solid colors. I have other rainbows I like better but for a more matte finish this is really good. Quality is as good as any other Sunlu, it won’t let you down

I had no idea how cool this 3d print would turn out either this SUNLU rainbow 01 filament. (Grinch) It’s absolutely stunning in person. The color swap as you can see in my photo is genuine and spot on. Will buy more! Rabbubu Labubu was printing with SUNLU rainbow 03. Both are scrumptious!
