Fang Xishui took a look at the viscosity of this, it was even more viscous than before, generally speaking, it had been a day and a night, so the color would definitely be a little darker, but this one was not dark in any contrast with yesterday's color.

She put a little liquid on her hand, and she was surprised, "How did you do it?" How long can this be stored? ”

"If you follow the way I made this, you can store it for a long time, about a few months, but although the shelf life is long, but in case it is evaporated by the air, it is not easy to say, I looked at this basic ingredient is that water is easy to evaporate by the air, especially now that the weather is hot. The water is evaporated and will still dry up. So you still have to use that kind of packaging and seal this up. ”

Fang Xishui agreed with him very much, "I think so too, that is, when I don't use it, I don't open it, but when I want to use it, I tear it open, but I don't know where to pour the package now." I could have designed the kind of bag that it would look like, but I don't know about it. ”

When Fang Xishui thought so, he turned his head and saw that some students in the class were eating snacks.

That snack bag is a yin and yang bag, which contains some dried seafood and the like.

One side is a transparent film, and then the other side is a tin foil film. There is a mouth in the middle that is sealed.

Is it possible to use this, and then seal the mouth completely with a sealing machine or something.

In this way, with this yin and yang bag, you can see from the outside that it is filled with a mask, and you don't have to worry about this mask leaking.

Thinking so, Fang Xishui looked at Huo Yanyi and asked, "Are you short of money?" ”

Huo Yanyi nodded: "Missing." ”

Although he is from the city, in everyone's opinion, he is a glamorous young master, but he knows in his heart how poor he is, and his family went bankrupt overnight.

In order to study, he couldn't afford the high tuition fees in the city, as well as living expenses, so he could only transfer to such a small town to live with his mother.

His mother, who is still lying in the hospital bed, spends a lot of money every day on medical expenses, and his mother's dowry has been sold out, and he has no extra money.

After hearing him say this, Fang Xishui was even more happy now, and asked him, "Then can you cooperate with me to do this business?" I'm going to sell this mask, you add chemicals into it to keep this mask shelf-life. If it is stored in this way, then we sold this mask bag from some manufacturers earlier, and then we can sell a lot. Don't worry, I'll give you money according to the share. ”

Huo Yanyi nodded without thinking, "Okay." ”

Fang Xishui thought of something again, and said to him: "By the way, I thought of one thing, if the lipstick is to be more colorful, so the lipstick must contain some heavy metals, and then the shelf life can be longer, do you know what heavy metals are?" Even the prescribed dosage will be fine. ”

Fang Xishui heard the little girl who likes makeup in the factory say that the color rendering of normal lipstick is very high, that is because there are heavy metals in it that comply with the prescribed law, but the heavy metal will not be fatal, and it will be fine, it is in a reasonable dosage, so the big-name lipstick will be particularly colorful, very good-looking.

Although her current lipstick is okay, she always feels that her lipstick is not bright enough.

Huo Yanyi was called a genius boy by others before, so it was difficult for him, "I know." ”
