I’m still kinda new and I was just wondering if there were any other ways to get chibis or bentos other than the spinner?
Yes you can trade your showcase items for chibis/bentos. I would recommend selling furniture you get extra even if you get a few chibis for a wallpaper or floor or stuff it stacks up on the long run^^
You trade certain items with a stat value in your showcase. You should ask the people to clarify which items they specifically mean. But they don't mean the kind of "mcs" that show up on your profile, that clubs have requirements for.
