Teramax! First of all, I would say that if you haven't used this pen till now, then go and buy it and use it.Although this pen is a little expensive than others but the quality of ink is perfect. you will find it very comfortable as it has very good grip.the refill of this pen is 3 times the refill of any other pen.so, you need not carry too many pens for the exams, only 1 teramax is sufficient for 3-4 exams.the design of the pen makes it look royal.the pen is very smooth.you won't find pen stopping anywhere.it will work smoothly till the refill finishes.conclusion-it is an awesome and great quality pen.
