High Quality White Chalk and Colorful Dust-Free Chalk for Kids

Chalk has become a powerful assistant in the field of education due to its unique material and texture. It is made of limestone and after fine processing, it presents a smooth and hard surface. This material allows chalk to maintain stable friction and clarity during writing, with smooth and less blurry handwriting. At the same time, the writing effect of chalk also has a certain degree of durability, and can remain relatively clear even in damp or friction environments.

Regular chalk is prone to moisture absorption, decreased hardness, and easy breakage when stored for a long time. The blackboards used in schools include cement boards, wooden boards, and ground glass boards. Due to different levels of smoothness on the surface of the blackboards, the softness and hardness of the chalk are also required. The new generation of dust-free chalk can change its softness and hardness at will, and will not slip or break easily when used on various blackboards. It also writes fluently, effortlessly, and has a good hand feel. Dust free chalk is a high-tech product that has been successfully developed in addition to cosmetic materials used in production. Environmentally friendly, non-toxic, dust-free, it is an ideal teaching and office supplies for modern teaching.
