If you don't want to go all out and use the design on every finger, you can even just put one on one nail on each hand and paint your nails a coordinating color.
All would look good with the other nails painted black, but you can also do a deep red for the black ones, and a pale pink for the one with the heart on it.
The nails can last for up to two days. To remove, just soak nails in warm water -- no damage is done to your natural nails.
Do you ever paint your nails or use press-ons with different themes?
