Selling items inside of a box

I have my selling item inside of a box. Each box contains one item. I’m planning on sending the box stacked in a pallet shrink wrapped. I want Amazon to only sell my product in the box without opening it. Do I apply both my box label and the individual SKU label to the outside of my box? If I’m sending 75 individual boxes, I have to label all 75 boxes with two labels? Does this mean that the customer has access to where I’m shipping it from on the box?

Correct me if I’m missing something. This is how I have it set up:

Boxes per pallet: 75
Units per box: 1
Prep not required
Unit labeling: By seller

And on the box label template they printed, it says
Single SKU

Qty 1

Pallet
