Kingroon High Speed PETG Printer Filament, Rapid Printer Filament 30-/s Hyper Printing Filament, Dimensional Accuracy +/-, 4 kg Plastic Spool (8.8lbs（Black&White&Red&Blue）

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.
