The Rimmel Day 2 Night Mascara has two ways to open it. One for volume and one for length. As you can see, the length end appears to go through the tube from the volume end to remove excess mascara. You can also see that it does remove a good amount.
I apply 3 coats when I used this. The first coat I use the length side, then the volume, and then the length again. At first I really did not like the volume end because it seemed to be very clumpy. I noticed by first applying the length then going back with more mascara using the volume end helps it look better.
I know my lashes aren’t long in the first place but I don’t feel like this mascara made them as long as other mascaras or as curled.
