I haven't used these products yet, the raincoat used before was very heavy. It's very inconvenient to put on. So I tried this raincoat, it feels great to put on. There is no sense of obstructing action. When I opened the package, I found a variety of raincoats in different colors, each of us can choose the color we like. I think we can take it with us on the field trip. Because it was raining hard days ago, it was I who carried a raincoat like this I won't get caught in the rain, I don't even feel it. It's a great feeling. A raincoat is long enough, it won't get your knees wet. That's not what other raincoats can do. So I suggest you take a raincoat like this. It won't take up your space and it will bring you convenience.

positive

It is very gentlemanly to the skin, very smooth, easy to take care of, will not hurt or cut your skin, the box is very good. Carry your bag and cleaning brush with you. The shaver itself looks and feels very good. It is light, easy to use, quiet and easy to hold in your hand. It is sharp and fast, and it shaves well. You can even shave in the shower because it is completely waterproof.
