Did not know the difference until I purchased some of my first Copies. Wow! That's all I can say (okay not really ALL I can say). They make an instant artist out of me and that's saying a lot LOL. Worth EVERY penny.
These are wonderful markers....they are pricey...but very nice colors and shades and they do make for a nice finished product! Yes they are worth the money!!!!! They really finish up and are impressive!
