JAYO Silk Dual & Tri-Color PLA Filament Bundle, Multi-Color Shiny 3D Printer Filament Set, Smooth Glossy Finish, Easy to Print, No Clog, 250g Spool, 8 Rolls, 2kg in Total

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.
