2. Trade is essential to produce traditional wooden pencils. Each country contributes important raw materials to make pencils. Plastic pencils, mechanical pencils, and ink pens are often used in place of wooden pencils. However, those writing products often require trade between countries to produce them.
3. International trade makes the manufacture of pencils possible. Without international trade, the availability, the cost, or the convenience of wooden pencils may change for people who use them.
