Accidientally purchased this 2.75 mm roll of filament for 1.75 mm printer. I did unseal the filament, but have dried it (as a precautionary measure) and re-sealed it in a vacuum bag.

"A most welcome variation on the woodFill filament. With corkFill we have opted for specifically sourced cork, combined with our PLA/PHA material. Its dark brown color compliments the lighter woodFill and makes for a great addition to your filament collection. You can give your prints a special look, like it was part of nature."
