JAYO Green PLA 3D Printer Filament 1.1kg Reusable Spool | ± Accuracy, Tangle Free, Vacuum Sealed, Smooth Printing, Compatible with Most FDM 3D Printers

Multi-pack bundles are the point — buying 4 or 10 spools at once brings the per-kg cost down sharply compared to individual purchases. Good for anyone running the same color through a lot of prints and watching their material budget.
