There is a certain style of pencil case where I'm not sure what it's called, or where to find one because I got one for a present once, and I was wondering if it would be acceptable to be asked on this site, otherwise which site I should ask it on? This seemed to be the closest site for this topic, but I'm not sure if it completely matches the "theme" of this site...
Questions on "where to find Product X" are generally considered a poor fit for Stack Exchange sites - they're very limited in their usefulness, and the store selling them today might not be selling them in another couple of months.
As for identification - well, product-identification is not really our thing, and writing tools and implements are really borderline here... I would say that if by "what the style is called" you mean a certain kind of pencil case, easily distinguishable from other types, whose use and utility are somewhat different... then that's a question about tools, and I think we'd be OK with it. But if it's a particular design or visual style, then that's not really a writing issue, IMHO.
By means of analogy, I'd say "What kind of tool should I use for hitting things together?" would be OK, whereas "Where can I find a hammer with a red wooden handle?" would be too localized.
Thanks for checking for such a borderline case!
