This 10-pack of 1.75mm PLA Filament from MakerBot contains one large, 2 lb spool of each MakerBot True Color filament - True Red, True Orange, True Yellow, True Green, True Blue, True Purple, True Black, True White, Cool Gray, and Warm Gray.
This filament is used with MakerBot PLA Printers to print 3D objects. Since PLA, or polylactic acid, is a bioplastic derived from corn, it doesn't emit toxic fumes when melted in the course of 3D printing.
Use this filament with 3D printers intended to work specifically with PLA, since they are engineered to cool the object rapidly after extrusion so that the PLA will retain its shape.
