While I don't sell on eBay (just buy, buy, buy) I have been selling on ChipTalk.net for years and one of the most consistent comments in my old thread there is about the quality of the packaging. You can check the thread if you want:

(There are some pretty nice photos of the Paulson licensed MARVEL superhero chips taken by purchasers peppered through the thread if you're interested in that sort of thing.)
Oh yeah, and I'm Canadian too.
Best regards,
