First, thank you for looking at our sale. We have been selling office equipment for over 30 years.   We are a very small, family owned and managed business. Also, please let me know if you are in need of high quantity or want ALL my inventory.  The exact quantity may be off (higher or lower), or be located in various warehouses. or issues due to the shortages going on right now.  Plus, I do not want to sell ALL my inventory from the listing as this "ends" my listing as a seller on eBay.  There are benefits in leaving a listing open for a longer term. Thanks for understanding.
