1. Is a PU notebook considered leather? 

Strictly speaking: It is not natural leather, but a synthetic leather made artificially. 

PU refers to polyurethane artificial leather, also known as imitation leather, super-fiber leather, or artificial leather. 

It does not contain any animal skin components. It is a synthetic leather fabric made through chemical synthesis. 

The "leather cover notebook" commonly referred to in daily life is mostly made of PU leather. 

II. Key Differences Between PU Leather and Genuine Leather 

1. Source of material 

PU Leather: Synthetic polyurethane coating + base fabric, artificial material, no animal fur 

Leather: Made from the raw skins of animals such as cows or sheep, a natural animal material. 

2. Appearance and Hand Feel 

PU leather: The patterns are uniform, the surface is smooth and neat, the feel is stiff, and the texture is rigid with no natural variations. 

Leather: Each piece has its own unique patterns and pores, with a soft and smooth texture, featuring natural leather texture. 

3. Durability and Wearability 

PU Leather: If bent frequently, exposed to strong sunlight, or left unused for a long time, it is prone to peeling, cracking and losing the coating. Its service life is moderate. 

Leather: Strong in elasticity, resistant to bending, it becomes more textured with use, is not prone to cracking, and can be used for a long time with proper maintenance. 

4. Waterproof and stain-resistant

5. Price-to-value ratio 

PU Leather: Low cost, affordable price, various styles, high性价比， suitable for students / daily office use
