In a small container, mix together the argan oil and Radiant Plum Colorant. Use a mini mixer if necessary to remove any clumps.

Place a nail polish mixing ball into each nail polish bottle. Add 2.5 mL of the color mixture into each bottle.

Slowly and carefully, pour the Nail Polish Base into each bottle. Fill each bottle to the neck.

Place a brush into each bottle. Screw the cap onto each bottle; doing so will adhere the cap to the brush.

Shake the bottles to thoroughly mix the nail polish base and colorant mixture. Once fully combined, the nail polish is ready to use!
