I purchased the 10kg blind box filament selection of 'C' and received 2 (B&W) PETG and eight various PLA rainbow colored filaments. Buying them in bulk is definitely a cost effective way to purchase filaments. The filament has performed flawlessly and will definitely make a future purchase when needing more filament. Shipping was fast; however, like a previous review noted, the box is a little large. My shipment had very minimal damage. My only suggestion to Sovol is provide more detail on what the blind box selections mean (there is an A,B,C & D selection but it does not signify details like rainbow, solid, silk, matte, etc.).
