I happened to accidentally stumble into a plastic food store while in Osaka a few months ago. I just looked up the name, and they have a web storefront! [1]
Admittedly all in Japanese, but the top part of the side bar shows you examples of pure fake foods, then the section under the "Sale" box gets you to fake-food style accessories, like USB drives, phone cases, and hair clips. Lots of pictures there to show the variety and quality!
(Edit: Sorry if this reads like a shill, I have no affiliation, and didn't even buy anything while I was there! Just took very touristy pictures.)
