How was the ball-point pen invented?
We know that the ball-point pen is one of the most useful inventions. It was invented by an American tanner named John Loud in 1888. And it really helps us write faster and makes our life easier. But sometimes the ball-point pens leak and they need refilling. But they are widely used in many fields. And the price is usually low. Ball-point pens are becoming smaller and lighter. They are really useful in our life.
可以嗎?希望對(duì)你有幫助哦.O(∩_∩)O~~謝了啊
