This product is one shade: Duomo Days, Isola Nights, a deep sapphire blue listed as opaque. The listing gives one size, 0.5 fl oz, and one form, gel. Check that you have an LED lamp before you order, since the listing calls for one but does not say whether a lamp is included. Screen colors can differ from the bottle, so compare the color photos shown here with what you expect.
Gel nail polish basics
Gel nail polish is applied in thin layers. Each layer is set under an LED lamp, which hardens it before the next step. This product's listing describes a multi-step system: bond, base coat, color coats and top coat, applied in that order. Because the lamp is part of the process, you need an LED lamp, as the listing calls for. Gel is usually removed by soaking rather than peeling. For this product, the brand says soaking takes about 15 minutes. Follow the instructions on your lamp and polish for each step.
