"Stock" is the word for the amount of material for sale, whats the word for material for office use?

I'm trying to do an inventory of the stationery here at the office.... but I'm not keen on using the word "stock" for the number of things we have because I think that's the word used for the actual products that will go out in sales.... what's the word used for the actual material that's used in the office?

Answer:
office supplies
office supplies, and unfortunately, stock of office supplies
Inventory or stock in both the office and at retal stores. Your picture is very cute, ma'am. :)
