I stumbled on a video for Cosmos Card Box and wanted one but found that they are not available anywhere. But, that was enough to want to find a fun card box I could work into some card magic. I want to put some cards, like a packet trick into the box and then pull out a different packet trick. Finding a box that you can show empty to your audience before you change the cards is challenging. The closest thing I have found is P-Case, but the video for it is not very clear about what it does and I'm hoping someone here might have some ideas. It is very difficult to search the forums for P-Case, so I'm starting a broader topic since there does not seem to be one about various options for magic card boxes. Thanks for sharing any ideas you have.

Check this one out:

Thanks Motown. That looks like fun. I do want it to look like a normal cardboard bicycle box.

I thought it might help to try and add some card boxes for you to maybe comment on.
