Santa Hats can be traded and sold. There have been several shops in Dion and Giran that are selling them from 800k-6kk. Thanks for info, found that it's a bit of waste to open the gifts and not worth it for ~40 archer. Well, I see your point, but if you're farming anyway, you'll still gain those event items eventually. Maybe you'll be lucky and get a hat out of it. It's totally harmless to try if you've farmed for exp. and gained the items as a bonus :). Cheers! Now I wonder why I haven't time to farm, but yeah.
