This is Hotzy, my most popular ACG.
I believe ACG and Gelish are the same product just marketed to two different companies because Louella Belle originally turned it down. Thats what my trainer told me anyway! Having about 30 of each (ACG & Gelish) I do find that Gelish is used more often. Be careful with samey colour between the two, I think Trist & Gossip Girl are the same x
