@falserealitygames I am sorry that you had a recent death in your family. That is never easy. When you are trying to run a business while dealing with heavy things, it makes a bad situation even worse in our minds. I urge you to try to take a step back and a deep breath.
First, you need to unblock your buyer. You have an open return and could end up in a worse situation if you don't keep the line of communication open. You already sent the return label, so eBay is not involved and that is a good thing. If eBay gets involved without you doing your part, you won't only lose but you will also get a ding on your account. We don't want that.
Second, "New" is not "New - Open Box." If it is open and has damage, even if that damage does not impact performance, that is used. I don't think eBay even gives you the option to list something in that category as Open Box and there is a reason for that. Often these items are expensive, as in the case of the plane you sold. eBay does not want there to be any ambiguity about what the buyer will get. Some people are collectors and they look for new because they want something that is still sealed in the box without cosmetic defects. You messed up here and should have listed it as used, then described the exact condition. You would have still sold it for good money.
If you hover over the information button by the condition, you will get a pop up that explains how eBay defines "New"
Before I even looked at your listings, I had a hunch your return policy was set to "seller does not accept returns." Please hear me on this: You are setting yourself up for problems by having that policy. You sell some pricey things sometimes and you are going to attract people who will take advantage of you because they know you are more likely to issue a partial refund since you essentially advertise you are resistant to returns. Those who take advantage know the eBay Money-Back Guarantee better than most. They often don't have to manufacture something wrong, because we as sellers often overlook even minor things. All a buyer has to do is point out something you didn't describe accurately and they've got you. At a minimum they will get a partial refund. Often they get a full refund by eBay and get to keep the item. I'm bringing all this up because this is likely why you are in this situation right now. Not saying this buyer is trying to pull a fast one on you, but you may not have gotten that negative feedback right off the bat either.
You do not get charged for the return shipping label unless the buyer uses it. Don't sweat about that right now. Yes, eBay will give them roughly 21 days to drop it off in the mail. A lot of times these people never do that. I offer 30 day free returns (60 days through the holidays) and of the last 5 returns I've had opened, 0 - non - zip have returned the item. The fact is most people don't want to have to pack something up, then go to the post office or wherever to ship it back. They are busy and decide that their time is more valuable. Now, this is a more expensive item, and if this buyer never mentioned a partial refund and just went for the return, then they are likely legit upset and will return the plane. This isn't their fault. This is yours. You listed it incorrectly. While I agree with what @babyers88 said in terms of reporting the buyer should the item be return in a different condition, in this case you listed it in the wrong condition. You need to own that and fully refund the buyer without reporting them unless they send you something back completely different.
You don't mention any damage in the listing, which means you misrepresented it. You have admitted that here. Your buyer has every reason to be angry. Rethink your practices and make a course correction. If you don't, you will keep finding yourself in this position.
