The SUNLU 250g Rainbow PLA Filament Bundle offers vibrant, fast color-changing effects with every 8 meters of print. Each spool is neatly wound for smooth feeding, and the 1.75mm diameter ensures consistent performance. Ideal for creative 3D printing projects, this 4-roll set (Rainbow 01–04) is perfect for making colorful models, gifts, and artistic prints. Though each spool is only 250g, the bundle provides a great way to experiment with different rainbow tones.
