Sometimes I just like to open my Helmer and play with all the polishes I have. Take them out, play with them and compare them. This way I found that Zoya Caitlin (C) and SpaRitual A World Of Compassion (AWOC) look similar in the bottle and was curious if they are dupes or not. I don´t call polishes dupes very often but I think that in this case I can. I think that if there are any differences between these two you just can´t tell. Both applied great and both needed two coats. It is only up to you which brand you prefer...Zoya or SpaRitual? :)
