1. Material: When selecting a pencil sharpener, pay attention to its material. High-quality pencil sharpeners are usually made of stainless steel or high-hardness plastic, which is more durable and less prone to wear. 2. Blades: The blades of the pencil sharpener should be sharp and safe. Ensure that the blade is sufficiently sharp to cut the pencil, while also taking note of safety features like protective covers for the blade. 3. Adjustment Function: Pencil sharpeners with adjustable pen clamp functions can accommodate different sizes of pencils or brushes, increasing their versatility. II. Purchasing School Supplies 1. Pencils: Choose non-toxic, environmentally friendly pencils with a smooth surface and no burrs that are less likely to break. For beginners or younger children, consider mechanical or triangular pencils designed to prevent slipping out of the grip area while writing. 2. Notebooks: Choose a high-quality paper that provides a clear writing experience, with thick paper and thread-bound notebooks being more durable. Select a notebook size and type that suits your learning needs. 3. Erasers: Choose soft, easy-to-erase erasers that prevent ink from being difficult to remove, resulting in blurred or damaged writing. 4. Art Sets: Select art sets based on the user (e.g., children, students, adults) and usage habits. Beginners may choose sets with instruction manuals for easier understanding of how to use the art supplies. III. Additional Considerations 1. Price: Do not only consider low prices when purchasing; instead, choose products with a good price-to-quality ratio. Comparing prices among similar products is more accurate. 2. Brand and Reputation: Try to choose products from brands with a good reputation as they tend to have more reliable quality. 3. Channel Selection: Choose reputable stores or official channels to purchase products to ensure after-sales service and quality assurance.
