I love these so much, I ordered a set for my best friend. We are both studying to become herbalists. With all the books we have, we use a ton of book marks. I love that they have growth patterns and history or other information on the back.I read all of these reviews talking about having to trim the serated edge and give them low stars, etc. This is indeed a booklet of 12 bookmarks. You have to separate them to use them. They are on a nice card stock type paper, fairly heavy. They are smooth, and feel nice in my hand. I think for about .17 per bookmark, there wouldn't be a lot of complaints....If you want a nice bookmark with the fringe, etc...this is not what you need. If you are a student, there are many different subject matters to choose from. The wildflower bookmarks are perfect for me!I think Dover has chosen an excellent way to offer 12 bookmarks for less than the cost of 1 heavy duty bookmark. You can laminate if preferred, they would still be cost effective. I love some of the other subjects in this brand of bookmarks and will be ordering more versions!
