The COLORFLO® refill was designed to extend the life of our quality brush. Susan felt strongly that it was necessary to make a refillable brush as it was more environmentally friendly.
To REPLACE cartridge:
1. Turn bottom of container all the way to the LEFT to unscrew cartridge - PAST the open position
2. Remove empty cartridge and recycle
3. Attach new refill by turning cartridge all the way to RIGHT to the LOCK position.
4. To begin use of COLORFLO brush, turn cartridge to LEFT until you feel a CLICK. It is now in the OPEN position.
