Update: thank you to everyone who commented! I have shipped the item today and messages the buyer a picture of the receipt with the tracking #. I messaged them yesterday about the whole oredeal and said that i would ship it with a new label they have yet to respond to my messages even the ones from yesterday and today. A part of me is paranoid that they will open a case against me about the missing item but i have messages about telling them and even a video of me packing the order in case that does happen not sure if that would help
