Wikipedia:Articles for deletion/Portable hole
I can't really recommend this one being kept unless some sources that actually discuss the overall concept in some depth are found.  Without that, the article is just a list of times similar objects have shown up in fiction, which borders on just being pure .  If no sources on the overall concept can be found, maybe this could have a light merge to The Hole Idea, which seems to have been the origin of this fictional oddity, in a kind of "Legacy" type section
