nail polish bottle
To clean out the nail polish bottle use some nail polish remover and shake the bottle till all of the nail polish is gone. Repeat as needed, then rinse out with water and let dry. Once dry get any color paint you want to use and pour some in the bottle. Shake the bottle to evenly distribute the paint threw out the bottle. Drain any extra paint. Then let the paint dry. Mines did not take long, about 15 mins. After that is done cut our pencil to fit the bottle. I just measured mine with the bottle and cut with a knife. Put some hot glue on the bottom of the pencil and place it at the bottom of the nail polish bottle. Remove the brush from the top and done!
