With this whiteout pen, you wouldn't have to wash over the same error again and again in order to cover larger cursive scripts. If you make a mistake while writing a letter, simply adjust the track on the side of this flattened utensil and modify the width of the liquid paper strip. The change in settings could cause the flow to be anything in between a fine pen-like line and a broad and inclusive ribbon.
There would be less visible mess while using the concept Modi-Roller by Younghoo Kim. With a steady hand, one single stroke could cover your inked page smoothly and lightly and in a straight line. Just gently press the button of the whiteout pen to let the correction fluid flow right where you require it.
