First of all, you need to register a trademark. It depends on how many categories you protect, and it costs 3, yuan less.

Secondly, find a factory with processing. Generally, small factories don't have too many requirements, but the less they ask you, the more uncertainty there will be. I suggest you find a bigger factory, which is more reliable.

It depends on which area you are in. It is better to find a factory near you. Sanitary napkins are discarded, and the logistics cost must be considered.

There are many factories in the south, but few in the north. It is said that there is a sanitary towel manufacturer in Miyun, Beijing, which is very good. It seems to be called Besute.
