For the syrup gels: they are very pigmented, but they still retain the syrup look. One coat is all you need for a classic syrup look! The colors look super yummy, just like Valentine's Day desserts. As V-Day is coming up, this collection is definitely a must for the V-Day look!
For the Nuance Gels: I am IN LOVE with the Nuance II gel. The picture doesn't even do it justice. It's like a galaxy in a jar. For both the Nuance II and III, they are perfect for 3D artists as they hold their shapes very well. I'd say the gels hold their shapes for a good ~10-20 secs. For Nuance I, it's perfect for you if you want to do textured chrome (or just textured designs). This collection is definitely a great all-in-one starter collection for any nail artists. :)
Overall, I'd recommend this collection to anyone, especially if you are new to the Korean gels community!
