Elastic Pen or Pencil Holders

I was so excited when I saw these. I feel like every journal should come with a built in pen holder but until then, these seemed like the perfect solution. Unfortunately they are so small! I was hoping for something that would clip onto the book itself but these don't open wide enough to do more that clip to a cluster of pages. That would be okay for a thicker journal (like the custom made) but for a standard bound journal it just becomes awkward because your book is unable to close flat. So I feel like it is a great idea but executed in a way that makes it ultimately useless for me. I will now have to look for thin journals to complement all the clips I bought.
