Good way for variety
I brought these as I work from multiple locations. A really good option to reduce the amount of pens I need to carry around. Two for one option. They do need to be stored horizontally or else the ink settles down one end which leads to the other end running out of ink quickly. I'll definitely buy more in future to build up my colour options.
