We use a 3-hole punch for a variety of projects around the house -- from punching my recipes as I file them to storing our product and travel research before making purchases.
We were planning on using this occasionally in our office. However i had to return the product because of poor design. The paper goes into holes below the punch instead of into the space where the punch cuts through. If the product were constructed better I probably would have been able to keep it and use it.
