kingroon Rainbow PLA Filament, 5 Colors Fast Color Change Silk PLA 3D Printer Filament, Shiny Smooth Multicolor Filament with +/- Accuracy, 1kg Spool(Candy)

Budget hardware maker that sells filament alongside its printers. Prices are low; the catalog sticks to standard PLA, PETG, and a few specialty variants. Not the place to shop for engineering materials.
