Amazon Basics Red PLAAmazon Basics is a new filament from Amazon. Likely from a Chinese supplier. Amazon does sell a sample pack if you want to see many colors in person. Amazon sells 22 different PLA, 5 different Premium PLA, 10 different PETG, and 5 different ABS colors. They also have some multipack options which can save money. Amazon Basics comes on a plastic spool in 1kg sizes. The spool has windows with gauges on the side so you can see how much filament is left.
