Before use, gently shake up and down with the cap closed. When using for the first time, or if the liner has been left with the brush tip pointing upward, the color may not flow readily. Check the color flow on the back of your hand or on tissue paper before applying.
Open and close the cap horizontally so the brush tip does not touch the sides of the cap. If foundation or other makeup gets on the brush tip, gently wipe it with tissue paper. After use, close the cap until it clicks and store horizontally. Leaving the cap off may dry out the brush and make it unusable.
