Each protector has 3 holes punched and a 3-hole punched black paper insert, and the protector opens on 3 sides (top, bottom and inside edge of the plastic which holds your paper on the 3 rings of the binder).

I love the sheet protectors.

, the protectors do not remain nice and flat

Hard to find now in office supply stores, I nearly always go to on-line resources for these invaluable plastic protectors

These protectors are perfect to protect important documents and to present them handsomely.

The protectors are clear and smooth as glass

There are times when I prefer the tradtional sheet protectors like these rather than the more common ones where you simply slide sheets in, usually from the top

Was okay for children's papers and had enough in case they ruin the protectors I put on their papers.

Once upon a time, this was the only type sheet protector available.
