Nice, haven't tried it yet.

Beautiful color, rosy brown, opaque...medium density and delivery on time.

Excellent 👌 👌 👌 👌 👌

Perfect 👍🏻

The gel polish is good, not too runny and almost transparent in the picture with the cat-eye gel polish on top, adding a bit of coverage; otherwise it's really transparent.

The gel is very thick; I applied gel polish to my nails for the first time, but it turned out quite well. It was more difficult to spread it on the nails because it's thick, but it doesn't clog, so maybe it's even better that it's thick. It arrived in Germany within a week. I recommend the product and the seller!
