Prusament is Prusa's own filament made in-house in the Czech Republic. It features a recycled paper central tube that makes it easy to refill. Only 1.75mm is available, with a tolerance of ±0.02mm. We've seen spools with tolerance of ±0.01mm.
Galaxy Black is black PLA with white/silver glitter. It does not need a hardened nozzle, but a 0.4mm nozzle orifice or larger is recommended. If used in an enclosed 3D printer, leave the enclosure door open to reduce chances of heatbreak clogging. Dry before use.
