For me making presentations goes with the job and I love scribbling on the flipchart so much more than PowerPoint. These come in a nice sturdy case and look so much more professional than a hand full of loose pens or those cheap plastic pens/sleeves that fall apart. The colours are great, and having 6 means you can add visual interest that the 4 colour set doesnt come close to
They dont seem to last all that long, either the ink goes (most brands seem to be similar, so not a complaint) or they get pinched by the audience! (a compliment of sorts I guess) For group work I still tend to buy cheapies and let them help themselves but for me at the front these are the obvious choice - if there is a nicer flip chart pen set I havent found it yet
