You can purchase nail art pens from Walmart and they will cost $5 to $10. Once you add a particular nail polish into a dotting pen, you cannot any other colour to the same pen unless. Hence, you might need to buy more than one pen if you want to add more colours to your nails.
Keep the cap onto the nail art pen and shake it well. You will hear the movement of cartridges inside the pen while shaking.
Press the tip of the dotting pen against any solid surface. Keep pressing it all the way down until you can see some ink at the base of the tip. This will denote that ink has flowed to the nib and your art pen is ready for use. Try out with some designs on your nail to practice using the pen and use a nail polish remover to clean it off.
Now it is time to get started with the actual process. Apply a base coat of polish on your nails with your regular application brush and let it dry for some time.
You can add a back ground colour to nails before further designing with the dotting pen. Choose darker colour for the background, such as crimson, violet, black or navy. Draw strips from the cuticle to the tip of the nails and let it dry completely.
Take your nail art pen and start designing. You can make simple dots, letters, hearts, flowers, strips or any other creative designs on your nails. Once you get expert in using the dotting pen, you can make more complex designs on your nails.
Let the nail polish dry for a while and then apply a top coat to add further shine to your nails.
