Hahaha, look at the ancient times, the Empress Dowager Cixi knew Maintenance depends on tools 😌 Now in the modern age, this tool has a nice name called "refa" hahahahahahahaha 😄 The queen mother's face tells you: beauty is more expensive One day when I was taking a selfie, I found that my flesh started to fall off! ! You say it's okay to have too much meat! ! It also fell down, it was unbearable! ! ! So I started doing my homework. In fact, there are two highly rated ones on the market. One is Refa and the other is N0. I have not used N0 and have no position to comment. I ended up giving up on N0 for the following reasons: 1) N0 needs to use gel, I don't know if the gel will continue to work after running out 2) N0's many netizens reacted more to the beans 3) It is necessary to use it when it is necessary to look good. In fact, it does not matter to me, because I will use it when I watch TV at home. But I wrote it because I felt that some girls might take a fancy to this. So let me mention it.
