1. Turn off the black locking part.
2. Leave the felt insert in the LINER and fill it with the Aquadrop bottle’s pipette drop by drop (approx. 20-30 drops for first filling).
3. Assemble and wait a little until the brush tip fills completely with colour by itself (hold upright, do not pump!).
4. The AQUA DROP LINER is ready to use. If the paint application is dwindling, simply refill the marker.
