Office supplies are essential for any workplace, and include items such as PENS, staples, erasers, notepads, toners, and post-it notes. PENS are a writing instrument used to make marks on paper, typically with a metal tip. Staples are small metal pieces used to bind documents together. Erasers are used to remove pencil marks from paper. Notepads are sheets of paper bound together, often used for taking notes. Toners are liquid or powder used in printers to create images on paper. Post-it notes are small pieces of paper with adhesive on one side, used for leaving reminders or messages.
