I'm currently working on a comic where one person gets shipped an innocuous looking item that turns out to be able to seal souls/magic. My original idea was for it to look kind of pocket watch but I realized that could be really cliché.
Does anyone else have ideas for what could work as a macguffin? Or small objects to look at as inspiration?
It needs to be small, able to be held in one hand. (She gets it in the mail.)
Have either a noticible button or a dial. (For activation)
And a relatively simple silhouette. (For ease of drawing)
And this might be a bit of a stretch but a noticible difference between when it's active and not.
Again, I'm not asking for someone to straight up design something for me, I just need some ideas to work with. Any help is appreciated.
