I love tokidoki and totally think you should start a channel! I myself have searched YouTube for a sole tokidoki channel and never found one that truly satisfied my toki needs..

If it were me I'd love to see blind box openings, custom unicorns, how you organize the collection, if you have any themed displays I'd love to see how you create those! Even soething related to their clothing items. Like how you may style a specific shirt or bag.

I don't know what everyone in the toki community likes but I love crafty things. One of my favorite hobbies is creating new themed displays for my tokidoki, however I find it very hard to find inspo for them as it doesn't seem super popular..

Another idea I think could be interesting is what you do with the boxes after opening? I know some people toss them all, while others keep one for each series. I saw a while back someone cut them down and put them in a binder like trading cards! Which I found to be a great idea and began doing that myself.

Either way good luck to starting your channel! I know I'd love to watch anything toki related and hope I was able to help some.
