Usually people have disposable mascara wands if they do other peoples makeup for sanitary reasons. But here is a little tip that can help if you find your mascara wand is getting yucky and clumping.
Use these instead of the brush it came with (when it starts getting old) because it is brand new and won't have dried up clumps on the bristles, making for a clean application!
Also, another quick tip if you want to continue using the brush it comes with, clean your brush before each use with a baby wipe to help for ease of application and less mess!
By pumping, we mean pushing the mascara wand in and out of the tube. Why? Because you will be forcing air into the tube which in return will end up dying out your mascara quickly! And that's also a waste of money! :)
