Unlock endless creative fun with KEZIBYN 32‑Color PCL Filament Refills, specially designed for 3Doodler Start & Start+ 3D pens. Our premium refills turn every idea into a tangible craft, making them ideal for kids, students, artists, and hobbyists alike. Made from low-temperature PCL material, these filaments are 100% non-toxic, BPA‑free, and safe for young creators. Unlike high-heat PLA, our low-temp formula eliminates burn risks, allowing for comfortable, worry-free use at home or school. Precision-engineered at 2.5mm diameter, they feed smoothly and extrude consistently without clogging or breaking, fully compatible with 3Doodler Start/Start+ pens. They adhere firmly to smooth surfaces like plastic for permanent projects, and peel easily off Lego, paper, and wood for temporary designs. Each 6‑inch strand features exceptional elasticity, stretching up to 35 inches—so you can complete large creations with fewer interruptions. This set includes 160 strands total (5 per color), with 32 unique shades: 21 bright solid colors for everyday DIY crafts 6 glow-in-the-dark colors for eye-catching night designs 5 soft pastels for delicate, subtle artwork All filaments come in a vacuum-sealed bag to resist moisture and maintain quality. Every pack undergoes strict quality inspection, backed by reliable 24‑hour customer support. Whether you're decorating phone cases, customizing stationery, building 3D models, or creating handmade gifts, KEZIBYN PCL refills bring your creativity to life safely and smoothly.
