Kingroon Silk PLA Filament, Multicolor Rainbow PLA Filament, Fast Color Changing 3D Printer Filament 1kg Spool, Dimensional Accuracy +/-, Fits Most Printers(7 Colors)

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.
