How to Choose Crayons? a. Material Selection: When selecting crayons, consider the materials used. High-quality crayons are typically made of natural materials such as beeswax and mineral pigments. These materials produce vibrant and fade-resistant colors that are safe for children. b. Brand Selection: Choose a reputable or well-known brand. These brands have strict quality control measures during production, ensuring the quality of the crayons. c. Selection Based on Use: Choose crayons based on the intended use. For indoor use, select crayons that are vibrant in color and less prone to breaking. For outdoor use, select water-resistant and durable crayons. 2. How to Maintain Crayons? a. Avoid Direct Sunlight: Store crayons in a cool, dry place away from direct sunlight to prevent the wax from softening and causing the crayon to deform or break. b. Prevent Moisture: Crayons are susceptible to moisture, especially in rainy seasons or humid environments. Therefore, store crayons in a dry place to prevent them from getting damp. c. Cover the Crayon After Use: After using a crayon, cover it with the cap to prevent dust from contaminating it or causing the wax to dry out and crack.

d. Regularly Check Crayon Condition: Regularly check the condition of your crayons for any breaks, color leakage, etc., and replace them promptly. Also, clean the tip of unfinished crayons periodically to ensure smooth writing.
