Shipping with eBay standard envelope

[lobby_of_hobbies_and_collectibles]

I sell a lot of trading cards and usually ship eBay standard envelope. I'm trying to ship something that sold but I don't have that option and I think it's because the listing didn't get put up correctly when I listed it. Is there a way to change it so I can still ship the card as eBay standard envelope.

You can't change the category after an item sells. You are stuck with shipping a different manner, either with ground advantage or PWE with no tracking.
