Better writing fluencyThe viscosity of the ink in a gel pen is between water-based and oil-based, and an appropriate amount of lubricant is added to make the ink more fluid and less resistant during writing. This design makes writing smoother without jamming or ink interruption. In contrast, the ink...

Acrylic Triangle Ruler have significant advantages among many materials, especially in terms of transparency, hardness, processability, lightness, dimensional stability, environmental protection, aesthetics, and applicability. First of all, the light transmittance of acrylic is as high as 92%, secon...

Acrylic is a plastic material with extremely high optical transparency, and its light transmittance can reach 92%, which is almost comparable to glass. Unlike single-color acrylic products, gradient acrylic uses special dyeing or laminating processes to gradually transition from light to dark or fro...

The main components of Highlighter Pen ink include solvents and fluorescent agents. Solvents are volatile. When the ink is exposed to the air, the solvent will gradually evaporate, causing the ink to dry. The speed of solvent evaporation is affected by ambient temperature, humidity and ventilation c...
