JAYO 3D Printer Filament Bundle, Glow in The Dark PLA Filament, 250g Spool, 4 Rolls, 1kg in Total, Luminous Green, Blue and Red, White

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.
