First of all, from the legal point of view, (the main bid and the washing bid) are your own trademarks or authorized by others. This is possible. Brand promotion is what you should consider.

As for whether there is such a factory? It depends on your quantity. If it's too small, go to a general tailor's shop. If the quantity is still relatively large, you'd better measure it with the manufacturer. Generally, you can sort out what you want in the sorting department and iron the packaging by the way.

Usually, ordinary factories don't want to do this kind of thing. It's best to have an acquaintance introduce you. It will be easier.
