The Dr. Grip pen is a best-selling pen all over the US and Asia. But Americans seem satisfied with the boring standard pen bodies that are available year after year in US office stores. But every year, Japan comes out with new color and special edition lines of the Dr. Grip pen. Most lines debut and end in Japan before we in the US are even aware of the opportunity that such a thing could be possessed. But now, the door has been opened and JetPens has brought in the newest color lines of the Dr. Grip pen from Japan. The Flash color series comes in five body colors including: black, blue, pink, red and white. The pen also features a layer of air between the rubber grip of the pen and pen body to allow a heat cooling effect, dispersing heat from fingers to keep hands cool even when you're under pressure. The pen is a delight to the eyes and a delight to write with. It will be a colorful companion to the work or school place. Black, blue, and red ink refills are available.
