I have memories of reading a book or series around 1996 in England.
It was, I think, set in England and involved some kids discovering a way to see the magical realm, which co-exists with the regular world. Being able to see it was conditional on something like holding a magical object.
A key macguffin of the series was "the talisman", a magical object that could only be safely touched by girls. I think there were witches too, mostly as an airborne threat to be avoided on whatever journey they were on.
