Can you tell which is which?
Nor can I, I only know because I know which fingers I painted Peridot on, which proves it's a dupe, a superduper dupe. There's no time to do a randomised control trial here so you're going to have to take my word for it. Formula, drying time, glossiness, duochrome greeniness was all pretty much the same. If I had to state one difference I guess may be Peridot is lighter but this is negligible to the untrained eye! Still can't tell? Have a guess and tell me!
