What single usage items are regularly used in offices?

There are many items that are used in an office that are used just once, and they should be avoided: paper towels, non-refillable ball point pens, plastic cups, cutlery and metal staples. Instead of using these, try using a mug instead of a plastic cup. Try using a refillable ball point pen. Try using a blow dryer in the bathroom instead of using a paper towel. Don't use staples, and try to reduce the amount of paper you print to begin with. Changes like these can really add up to make a big difference.
