I do not have a "magic shop", but I do have a trick for sale (while they last).
Years ago I marketed a magic/origami trick with Jeremy Shafer called "Fusion Loops".
It's a pretty cool trick, and it is still available.
Contact me if interested, and I can make a deal. Bulk discounts are available.
Made of specially printed Tyvek paper. With instructions.
