SUPERIOR ESSENTIALSBookmark/Weight-Page Holder-Set of 3-Green-Black-RED Holds Books Open and in Place-by

This page holder is a waste of money I’m disappointed as it slides down the page it states that it’s not supposed to slide this is so annoying.

Great idea, works well. I got it for holding down the pages of reference books while typing - works fine. It's also handy for reading a book while you eat.

So useful if you struggle to hold a book open, it really works well.
