This coloring changing filament makes a shiny pattern going from a metallic silver, bronze, blue, and then repeats. The filament adhered to the buildplate very well, I almost couldn't remove it without a flexible build plate. In terms of individual layers there was no separation and the filament blends so well I can hardly notice layer lines unless up close. I printed a wolf model using an iPrusa MK3.9 on default prusa PLA settings with a layer height of 0.2 and temperature of 215C. The filament box includes a reusable bag to store the filament when it it use, this is fantastic and I think more companies should do this. There was also a first for me, it even includes a 5M strand of "cleaner" filament that is meant to be used between material type changes to keep nozzle from clogging. I thought that was pretty neat, I'm usually doing cold pulls when changing from Petg to PLA. The cleaner filament is a little more tacky than PLA which seems to grab any residue in the nozzle and pull it through. Super satisfied with this filament and like the variety of colors available.
