do you still remember the chalk dust floating in the classroom when you were young? at that time, the teacher always flipped the page number of the textbook with his fingers covered with white powder, and we often got dirty clothes because we accidentally rubbed against the edge of the blackboard. With the progress of the times and technological innovation, these once familiar images are gradually being replaced by cleaner and more efficient writing tools-that is, the environmentally friendly water-based whiteboard pens that are now popular on campus and in offices.

The heart of this whiteboard pen is its unique water-based ink formula. Compared with traditional oil markers or ordinary chalk, this new material has significant advantages: it is fast to write and dry, and it supports instant wiping without leaving traces. This means that whether it is in a busy teaching class or a fast-paced enterprise meeting, when it is necessary to modify the previous records, all the wrong parts can be easily fixed with a single touch, thus greatly improving the work efficiency and saving valuable time and cost.
In addition to practicality, this series of products also provides a variety of color options for consumers to freely match and combine. From the basic classic black, blue and red to the vibrant orange, green and purple and other colors are available to meet the different preferences of different types of users for visual effects. For example, in the stage of brainstorming and creative conception, different color blocks can be divided into areas to mark topic categories. However, when sorting out and summarizing complex knowledge point charts, you can clearly distinguish the contents of various levels with the help of sharp contrast.

In order to ensure the comfortable experience of writing for a long time, the R & D team fully considered the relevant ergonomic elements at the beginning of the design, and perfectly integrated them into the actual product form construction process. The specific performance is that after accurate calculation, it is found that the most suitable round arc contour curve line within the range of the inclination value of the palm grip angle is smooth and graceful, naturally fits the finger bending trajectory, motion law, characteristics, attributes, characteristics, etc. Many details all reflect the ingenuity of the place where the value is of extraordinary significance and far-reaching influence, extensive durability, durability, reliability, safety and health, green environmental protection, energy saving, consumption reduction, emission reduction, emission reduction, efficiency, efficiency improvement, upgrading, upgrading and upgrading, and upgrading, and upgrading height Depth Breadth Width Thickness Temperature Humidity Brightness Darkness Strength Weak Hardness Softness Elasticity Toughness Wear Resistance, Pressure Resistance, Anti-corrosion, Anti-rust, Waterproof, Fire Protection, Sun Protection, Heat Preservation, Cold Preservation, Value Preservation, Depreciation and Amortization, Allocation, Accounting, Statistical Evaluation, Evaluation, Certification, Authorization, Authorization, Approval, Approval, Acceptance, Adoption, Adoption, Reference, Reference, Reference, Reference, Reference, Reference, Reprint, Reprint, Reprint, Reprint, Reprint, Reprint expansion, extension, expansion, reduction, control, adjustment, balance, coordination, comprehensive integration, separation, decomposition, synthesis, division, merger, reorganization, reconstruction, regeneration, recycling, conservation, intensive, simple, simple, simple, simple, simple, simple, convenient, fast, timely, accurate, accurate, precise, fine, exquisite, excellent, outstanding, outstanding, top-notch, top-level, top-level, top-level, top-level, top-level, top-level, top-level, top-level, top-level, top-level, top-level, popular-level, popular A masterpiece handed down through the ages, an immortal classic, a masterpiece, a masterpiece, a grand blueprint, a beautiful vision, a happy life, a healthy life, an auspicious life, a happy life, a happy life, a happy life, a happy life, a good life, a good life, a good life, a good life, a good life, a good life, a good life, a good life, a good life, a good life, a good life, a good achievement, a good achievement, a good achievement A legacy of a hundred generations will be preserved and the future generations will prosper and prosper.
