I'm still measuring the other brands. takes me close to an hour to do one -.-
I need to correct my method. Instead of using 3ml for the oil and coffee, I used 1ml because I realised when I measured it, how much 3ml actually is. And trust me, it was a lot. LOL and to think I was gonna use 5ml x_x
Oh, and I used the averages of three points on the makeup ring because it wasn't exactly consistent
