These sturdy page protectors (sheet protectors) are made from heavy 7.5 mil polished clear vinyl and are very easy to see through. Tear resistant. Many other page protectors are less than half the thickness and rip easily. 6 hole page protector outside dimensions are 4 ¼ x 6 ¾. The hole punch area and reinforced seams take up about ¾ inch leaving an inside area for pages up to 3 ½ wide x 6 ¾ high. Some sheet protectors are too wide and stick outside of your small binder when it's closed. Our sheet protectors are just the right size and fit perfectly in most standard sized binders. Our matching binders are also available (see accessories below). Set of 12 sheet protectors.
