I just realized I have huge stock of about 5,500 disposable face masks now I know they are worth a lot.
Best way to sell would be to just send to amazon fba but there’s a lot of news about them closing down losing and accounts for anyone that prices there item to high. My question is how do I know the best balance getting most money I can without getting shut down and also they come in 10 pack should I repack them to one pack each selling them individually?
Assuming you had time and skills to get a basic Shopify store setup in a couple days, I would suggest building your own store. That way you would own the traffic and transactions that are coming in through there.
The traffic will be just as effective to come FROM those same areas that have been suggested, but the transactions occur in an area that you control.
The packaging question is dependent on how you ship them. If you have the basic infrastructure, you could package them individually and make more profit. But if you don't, and mostly want to offload them easily, then I would suggest keeping them how they're currently packaged and send them out.
Hope that helps!
