I have several of these pressed glitters and have now had a chance to play with most of the colours on my eyes. The formula is wonderful as it does not have any fallout! I apply these glitters with my fingers and with a small synthetic brush and I've had no issues with either of the application methods. The glitters also stay on for a long time and when you're ready to take them off, they wash off easily with some soap and water or with a makeup wipe. I love these and am definitely looking forward to more colour options in the future!
