The term 'not mass-produced' can be used to describe items that are HANDMADE, custommade, or tailormade. HANDMADE items are created by hand, without the use of machines or tools. Custommade items are made to order according to the customer's specifications. Tailormade items are made to fit a specific person or purpose. All three terms refer to items that are not mass-produced, meaning they are not produced in large quantities for sale to the general public.
