From Guild Wars 2 Wiki
Gift Exchangers are seasonal vendors who exchange unwanted gifts for Wintersday items.
- Originally they would only trade items for Ugly Wool Clothes. In 2014, Mystical Cogs, Drops of Magic Glue, and Wads of Enchanted Stuffing were added as items they would accept for trade. In 2015 and years since, they no longer accept the doll materials, but added using karma and snowflakes to purchase items.
