This is Cookiecad Dual Unicorn Silk.
It's silk pink on one side and silk blue on the other and prints both at the same time creating a unique color changing effect!
Silk PLA is super shiny and easy to print with but your prints will be more fragile than classic PLA; that's just the nature of silks.

Not recommended for structural parts or cookie cutters. This roll is so much fun to print with!
