Do you make money by selling diy bags?

Those who make money and sell diy material packages are small commodities with small profits but quick turnover. The cost of such goods is often relatively low, and there is basically no need to worry about expiration. If the sales volume is good, the profit of this product is still quite optimistic. The key lies in how to attract passengers in the early stage. If we can cooperate with kindergartens, parent-child care and other institutions for a long time, the sales volume will be better.
