Sold a guitar Internationally and I’m nervous about shipping

I sold a Martin lx1e to a buyer in France. I’m located in ireland. It sold for €500 including shipping. The shipping came to 64€ and reverb seem to have taken about 42€ for there fees. I don’t know how that breaks down.

Anyway I packaged the parcel well and it’s gone this morning. The buyer doesn’t have any feedback and I’m really nervous. I’ve been scammed before as a buyer on depop but never as a seller. He paid straight to my card and reverb emailed me saying the money will be in my account Monday.

What are the chances of this going pear shaped? I’m really stressed over it and I don’t know why. Even the chances of the parcel getting lost, I’m not insured at all through the shipping provider.

Anyway, any replies are greatly appreciated.

Stay safe everyone
