The first one worked out so well, I made another one for the other pens in my purse pen case. This one is made from two index cards and masking tape. I may have to reinforce it or replace it as time goes by, but it's working beautifully so far. A few pens and my Tombow pencil are still free floating, but having these two in here make a world of difference. Finding pens is so much easier now and an added bonus:
I can stand them up in the pen case to make for easy accessibility. Color me happy.
