Amazon.com: Polymaker Glitter PLA Filament 1.75mm, Galaxy Dark Green PLA 3D Printer Filament 1kg - Twinkling Filament, Dimensional Accuracy +/- 0.03mm (0.6mm Nozzle Required) : Industrial & Scientific

This is the closest to mystic brown i have found. This is the first filament i bought that required a .6mm nozzle. After two clogs i went back and read the about this item. should have paid more attention before purchasing. probably a great filament but i'm not willing to change my nozzle mid project just to print this . beware the required nozzle size.

So far I have liked PolyMaker filament but I just unsealed this roll and the 1st 100 grams or so were all cracked. I've got about a dozen 24-inch long pieces, a 6-foot piece, a roll that was at least a few layers worth of spooled filament, and a few other pieces of varying lengths.Not sure if it's the filament itself, some issue with shipping caused the filament to break if the filament has too much moisture or if it was too dry, I'm not sure.
