These are great for use in our manual comb binding machine! Use them for lots of different reports and projects at school! They hold up well to kids opening and reading reports. Nice for kids scrap booking! Imagine all the possibilities you can bind lots of different things from photos scrapbooks reports art projects birthday cards and more! Make great gifts for grandparents. Most teachers use these so they are a great teacher appreciation gift too! Get some in different sizes for different projects. I always keep them on hand!
