Query: Nothing but Zebra Sarasa!

I've been using Zabra Sarasa Gel Pens for a while now...it gives you a smooth writing and I feel very comfortable while using those pens. I've been using these set of pens on daily bases until the last gel during the Undergraduate & Graduate School. it makes my notes so readable and efficient for later review.
