I did try them with monomer and they did not work. They wouldn't harden. It actually became kinda like a sand consistency. I tried it with purple Phoenix and secret Nail affair monomer. If a dip powder is a 2 in 1 then they can be used with monomer but these are just for dip. I was pretty bummed about it because I am not a fan of the dip method lol I will try to do a video to show what happened when I tried the monomer 🥰🤗
