Key Features and Use:

• Function: It dispenses an opaque, white fluid to mask or obscure handwriting, typing, or other markings. 

• Design: It is shaped like a pen, typically with a fine metal needle or fine-point tip for precise application. 

• Fluid: Contains a fast-drying, white liquid or paste (a mix of elastic polymers, pigment, and a solvent). 

• Application: The fluid is released by gently pressing the pen tip down on the paper and sometimes by lightly squeezing the barrel of the pen. The fine tip allows for correcting small mistakes, like single letters or thin lines. 

• Drying Time: It is formulated to dry quickly (often within seconds), allowing you to write over the corrected area sooner than with bottled correction fluid. 

• Result: Once fully dry, the white fluid creates a smooth, opaque surface that can be written or typed on. 

• Before Use: It is generally recommended to shake the pen well before use to ensure the fluid is properly mixed and will flow smoothly. 

• Common Brands: Popular brands that manufacture correction pens include Liquid Paper, BIC Wite-Out (e.g., Shake ‘n Squeeze), Tipp-Ex, and Pentel.
