There are many patents for not sharpening environmental protection pencils. Why can't they replace wooden pencils?

1, environmental protection pencils generally use recycled paper instead of wooden pens, which is worse than wooden pens. Moreover, environmental protection pencils are mixed in the market at present. Some inferior environmental protection pencils are branded as environmental protection, but there are some problems such as eccentric core and skewed penholder, which makes consumers reluctant to buy environmental protection pencils again.

2. Environmental protection pencils usually have a low unit price, giving consumers a feeling of "low value", and low prices often give people a psychological hint of "poor quality".

3. Wooden pencils have more historical significance than environmental protection pencils. This kind of thing that respects tradition is hard to be replaced by new things for a while, and may be replaced later.

4. The wood pencil industry is also in transition, seeking economic fast-growing forests as raw materials to meet the needs of people's "environmental protection" concept.
