I know they discontinued them around the beginning of 2019, but I think it would be a good idea to bring them back for 2020 and here are some ideas following mystery boxes.
1. A mystery box containing previous items ( whether if it is bento items, or items from previous light and dark boxes, or a box that contains popular items from a certain year? etc)
2. It would be a great idea for users to submit ideas to OW staff for a user designed box. I mean they took ideas before, so why not put some in a mystery box fully based on creations?
Let me know what you think in the comments, and please thumbs up this suggestion =]
