Perfect for you the seller, not so for the buyer if anything goes wrong.
If a third party is involved, that is, the buyer themself is not coming to collect and inspect the item, they lose all eBay protection as they then cannot claim for item not as described.
A bank transfer is as good as cash.
Your buyer here is the one who is being trusting, and going ahead with a sale with an item he has not inspected.
Carry on with this sale with confidence.
