about Stealth seller send turn shipping label

[allsmell]

Hello
I have several stealth seller account, some time buyer ask for return. How can I send them the return label? If I create it on eBay system, several account use the same return address is very danger.
There are just 3 options when I choose accept return:
1 , buy a label on eBay(i need to type the return address on eBay system
2, Upload your own label
3, confirm you already sent a label
Which one is best for stealth account?
thank you

Send your own label

I use external postage software to email return labels for all of my accounts, and all returns go to the same address.
