The pen both in appearance and use are awesome. Pen is not that heavy however a bit thick. The roller ball pen is of fine tip I.e. 0.5mm, though I prefer tip of 0.7 mm. There is only one problem I am not able to locate refill of any tip.. would request the company to supply refill worh different tips of 0.5 mm or 0.7 mm and of different ink colors.
