Yes, tell me about 52 glue. Is it environmentally friendly?

Some are environmentally friendly, and some are not. Shops selling 2-3 yuan are almost environmentally friendly, and the ex-factory price is .3-.8 yuan. When they go to wholesalers and then to stores, they become 2-5 yuan, and the wholesale price of our ordinary environmentally friendly 52 glue is basically 2.5-5 yuan. It is too expensive for traders to get to the market, so our glue is basically wholesale to factories. What they need is quality.
