You items are rather high end.
No returns does not mean no returns as you should know.
If the claim is opened...I would ask buyer to return it for a refund.
Not as described means you pay for return shipping
Emails and any photos taken will not matter in a claim usually.
And doing emails back and forth only makes the buyer more upset...thus there's always that feedback to think about.
Doing nothing and let eBay handle it means eBay will refund them and buyer keeps item since you have "no returns".
Buyer might know the ins and outs of refunds. Of course, block the buyer and check their feedback to other sellers to get some idea as to is it an honest buyer or an honest mistake. I have made some mistakes mailing items out.
