We like everything about this paperweight for a book.  Enough weight to keep pages open, not to heavy if you need to bring it in your bag because you are working on a project. These are particularly helpful when you are working on taking notes or inspiration from a page in a book and you need the book to stay open.

It can stably hold open books due to its shape that nestles against the open pages.

Simply place it, and you can easily turn the pages with minimal effort.
