This is literally the best gel ever it has an amazing colour and amazing consistency i will use this till the day i die

❤️❤️❤️

Such a beautiful color, more on the liquid side so it self levels beautifully. wouldn’t recommend for beginners tho

Highly recommended, excellent quality and price.

I will always recommend these gels, they are very good.

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!

The product arrived quickly, the jar was larger than I expected, haven't tried it yet.

Good product, no odor, dries the lamp well in 60 seconds.

Its texture is easy to control and the colors are wow, nude and beautiful.

It's wonderful, I love the result and the durability of the product; I would buy it again without a second thought.

❤️ ❤️ ❤️ ❤️ 🥺

Everything is well packaged, super color, I love this brand.

Very beautiful color, easy to work with.

The gel is wonderful, not the first time I've used it. It's thick, doesn't heat up, durable, and cures perfectly. The color matches well. On the nail tip, it looks almost white with a slight creamy tint.

Everything is great.
