Pencil is manmade. It is typically crafted from materials such as wood, graphite, and clay, which are processed and assembled to create the writing instrument. While the graphite used in pencils is a naturally occurring mineral, the overall construction and design of a pencil are the result of human innovation and manufacturing.

Pencil
A pencil has a definite shape due to its solid structure, which is maintained by the materials used in its construction, typically wood or plastic. The rigid nature of these materials allows the pencil to retain its form, providing stability and functionality for writing or drawing. Additionally, the manufacturing process shapes the pencil into a uniform design, ensuring consistency in size and usability.
A pencil factory in the US may need to import wood (cedar or other types) for the pencil shaft, graphite for the pencil core, and possibly certain chemicals or additives for the pencil's manufacturing process. Additionally, raw materials for the eraser, metal ferrule, and the paint used for coating the pencil may also need to be sourced from other countries.
The amount of water used to make a pencil case can vary depending on the materials and production process. However, on average, it takes about 10-15 liters of water to make a pencil case, considering the water used in manufacturing the fabric, dyeing, printing, and finishing processes.
Asphalt is a mixture of petroleum manufacturing by-products, natural hydrocarbons, gravel, and rock used for paving.
The inputs of making a pencil include graphite or lead for the writing core, wood for the casing, clay for binding the core material, and metal for the ferrule that holds the eraser. Other materials like paint, lacquer, and an eraser may also be used in the manufacturing process.
