Using your SpaRitual Retro Collection Kit is a breeze. First, select the shade you like from the 216 bottles of nourishing vegan nail lacquers. Apply a base coat on your nails before adding the color lacquer. You can use the pre - painted nail palette to see how the colors look side by side and make your choice easier. When it comes to displaying the kit, use the header and magnetic strip with images to make an eye - catching setup. As for maintenance, keep the nail lacquers in a cool, dry place away from direct sunlight. Make sure to close the bottles tightly after use to prevent the polish from drying out. Remember, the large display is not part of the kit, so if you ordered it separately, assemble it carefully according to the instructions that come with it.
