Amazon FBA How To Send Your First Shipment To Amazon

Hello everyone,

I’m artisan making hair clip and house decoration, I’m trying to open a store on Amazon Handmade with FBA option. If I understand correctly, I must send my products to Amazon warehouse, but I don’t understand how to pack my package.

For example, I want to send 5 items Hairclip-A; 5 items Hairclip-B; 2 Decoration-A and 10 Decoration-B. Do I have to print 5 Hairclip-A labels, 5 Hairclip-B labels, 2 Decoration-A labels and 10-Decoration-B labels, stick them on each item and after that put all my items into 1 box (22 items of 4 different type products) or I must put 4 types of products on 4 boxes?

Thank you for your help.
