Though a bit on the more expensive side, these are the best disposable wands I have used in my pro career! Perfect sized brush is suitable for most mascara formulae. Also, not too thick to prevent you from getting into inner eye corners for more detailed application and not too thin to take away from volumizing! Have used these to apply brow gel (for a tint effect) as well and love the fact that they hold product so well. On a personal level, if you are looking to pump up the volume of your current mascara or find that your lash brush (spooly) gets too filled with product (despite cleaning efforts) to be saved after years of use (I've personally gone through at least four of them now), this is definitely a disposable worth while.
