Gently insert the refill into SENSAI CONTOURING LIPSTICK HOLDER that comes separately.
Keeping the cap on, firmly push the refill into the holder until the line on the refill is hidden. After setting the refill, take the cap off.
If the line on the refill appears during use, firmly push the refill into the holder again.
The refill can be changed and multiple colours can be used with one holder. In that case, do not throw the cap away.
