Product Description

HELLO3D Silk PLA Rainbow C (Metal Color) is a multi-color PLA filament with a silk surface effect and an attractive, smooth color transition. Thanks to the "silk" formulation, it creates glossy, almost metallic-looking prints that minimally reveal layers. The Rainbow C variant offers a metal-toned palette for a premium look without painting.

Why you will love it
