This thing is quite good, endorsed by Xiao S. Sleeping stickers can lose weight and the effect is not bad. However, the price is quite high. You need a box from 200 yuan after the discount.

But I heard that you can apply for it for free now.

Only the postage from 20 yuan is required.

You can try it if you are interested.

Anyway, more than 20 yuan is not expensive. I have a website.

I can tell you if you want.
