I’m becoming a huge fan of Proto-Pasta’s opaque glitter filaments. The glitter is often more subtle than other brands but it still leaves a feeling of magic in the color. There are no concerns printing with a normal nozzle. The filament itself prints easy and hides lines and imperfections well. There is discussion about layer heights affecting the glitter shine, but I didn’t notice it in testing. This filament is normally sold in half kilogram weight on a cardboard spool.
