Excellent quality and robustness. Puncher flexible because you can position the 6 holes where you want, practice for workbooks of different formats. As against a zipper for positioning the paper based on its size, as it exists on other drills, have been useful. That's why I put only 4 stars to this product.
ATTENTION: the product supplied is that corresponding to the large spike in the photo. I do not know why the photo shows a second too.
