Black Gel Ink Rollerball Pens 1.0mm Regarding the breathing holes on the cap and bottom of the pen: The breathing hole can maintain consistent atmospheric pressure inside and outside the pen, making it easier to remove the pen cap. Breathing holes are also called life-saving holes. When using a pen, some children may put the pen cap into their mouth out of curiosity. In the event of an accidental swallowing accident, this breathing hole can ensure that the respiratory tract is not completely blocked before rescue. We will make every effort to ensure the quality of the pen refills. So please don't worry about the problem of refill leaking. About the label: This pen has three types of nibs, and you can choose your preferred thickness according to your needs. This is one of the information displayed on the label. The barcode label indicates that this is a pen that has passed quality inspection. Due to the inconvenience of displaying barcodes other than Amazon product labels, this is not specifically shown in the product images. About the Pen Body The pen has a matte surface, which provides a better grip and more comfortable touch.
