would I be better off doing sealed box

It depends how accurately you can replicate the original packaging.

wrong item received

It's certainly a viable method that's suited to any company who has an Inventory of stock.

You know how It works, so I won't explain It.

wrong item inside box?

This Is either a manufacturer error, or you (seemingly) purchased someone else's return.

Given the Item value, I'd say they'll Investigate It thoroughly, which can complicate the SE. You still have (obviously) the DNA and the boxing method available.

Thank you sir
