Here’s something that struck me as unusual: a top-opening lab notebook.

It looks a bit like the Book Company lab notebook I reviewed, but that was side opening, as is every other lab notebook I’ve seen. Also, this one is different in that the pages are printed on only one side, which might appeal to notebook users who like a mix of lined and plain pages.
They’re $7.99 here: Scientific Notebook Company. Other styles are also available.
