Boundary of a Memory is a densely packed full coverage glitter, it is made up of black, silver and copper glitter. The copper glitter is not easily visible on the nail, however it breaks up the black and silver glitter and warms up the polish as a whole.
Surprisingly I only needed two coats for full opacity! The formula was a bit thick, and thickened up the longer the bottle was opened, I would recommend thinner be incorporated into the polish between uses. The formula wasn't the worst to work with but it wasn't amazing either. The good thing about glitters is that it is easy to fix and manipulate the glitter on the nail to fix any imperfections or mistakes.
I really like this glitter because it's sparkly but kind of dark, and I love that full coverage is achieved in two easy coats with fast dry time. I am currently on day three of wear and have gotten a few small chips here and there mostly due to my hands evening constantly wet in preparing food/washing dishes.
