The bottles need to be labeled, takes a long time to dry, and they aren't near as dark as the images.They do change colors and for the price it is the cheaper of the color changing polish but you do get what you paid for.Pretty and held up beautifully.If you want your nails done for a day or less, great! But if you want the 21 day manicure that it promises on the box, get something different!!!I like the color changes. I dont like how there is no colors listed on the bottles. The bottles are all black and you can't tell what they are without opening them.Love the way these go on! The "warm" color is very transparent so it's very helpful to have a solid color underneath the color changing polishColors are vibrant with long lasting shinePicture should say it all. That’s only 2 coats.These are very thick and not easy to apply... They do change color but wasn't very happy that all the base color of them were mostly pink, then changing into other colors I didnt like either lol. I think I was sent the wrong colors but wasn't too impressed with these.You would think the end color is red, but alas, its pumpkin orange. Theres 2 oranges and i thought the orange on the sellers page was the other color. Little bummed about it to say the least.The colour in the end is supposed to be orange but I got a coral pink. Aside from that some of the colours are really nice just a few are more pink than orange.This product is the worst, the brushes fell out of the stick part & the product was hardening as soon as I opened the bottles. I tried my best to work with what I had & did my daughters nails & within 24 it all fell off.
