Colorful Refill Filaments for 3D Pen (5m PCL filaments)

PCL (Polycaprolactone) is a biodegradable, biocompatible, and non-toxic material. It is food-grade, eco-friendly, and specifically designed for use with 3D printing pens. With excellent flexibility, low-temperature molding, and enhanced safety, it is perfect for children to use.

Reusable & Eco-Friendly
Used filament scraps can be repurposed! Simply place them in 50°C (122°F) warm water for about 5 seconds. Once softened, the filament becomes as malleable as modeling clay, allowing for creative reshaping while reducing waste.

Safe Low-Temperature Printing
PCL filaments work at a temperature close to body heat, making them safe to handle. With a 3D printing pen, kids can even create directly on their palms, unlocking endless creative possibilities while staying safe.
