consistent colour, well finished, good grip on minimal sheets of paper

These are good quality durable stiff plastic, that doesn't shattered when trimmed , so these can be used for a variety of paper sizes, they have a cut out at one end to make sliding on to your collection of papers easier.They come in a Neat Tidy well packaged sturdy box, holding more than I will probably every use.Now I have to confess that I use them for a non intended purpose!These make great Knife edge covers, I trim them to length and then cut off a corner on one side at both ends to provide an easy access for the blade to slide into.

I bought this product for our guinea pigs coroplast cage liner to protect it against being nibbled.The curved end of the spine bar makes it easier to slip the binder onto the coroplast. You can also cut them with sharp scissors to fit shorter sections.I would highly recommend these if you are looking for something to prevent your small animals chewing their coroplast base.
