The packaging of this product is very good, very strict, and the design is very scientific.


The product I bought is really good. The other ones I bought before have a lot of particles in it. They are not smooth to the touch. I don’t know how to use it, and the beauty stitches I bought make it. I really don’t have to say.


The effect is very good! The smell is very small, almost no smell during construction.


The quality is very good. I made it at home by myself. It's okay. The effect is good. The quality is indeed better than the price bought in other stores.


The smell is very small, the gel is translucent, it is smooth to use, and it dries quickly. The anti-mildew effect needs time to test.

It is forbidden to mix other non-designated materials, especially beautiful grout. This is a substitute product, please do not mix it. After a few years, the grout will turn yellow and black. Even if there is a good caulk, it is recommended that you choose a special grout. This is the difference between caulk and beautifier.
