In economics, a durable good or a hard good is a good that does not quickly wear out, or more specifically, one that yields utility over time rather than being completely consumed in one use.

Consumables are products that consumers use recurrently, i.e., items which get used up or discarded. For example consumable office supplies are such products as paper, pens, file folders, post-it notes, computer disks, and toner or ink cartridges. This is in contrast to capital goods or durable goods in the office, such as computers, fax machines, and other business machines or office furniture.
