Colorful Pen

This morning I was very happy to buy many different colors to set up my pen holder, and I collected different pen brands to use. Mistubishi I bought 2 pen holders for 5 colors and 3 colors, after all, it is the brand that I used for 12 years. Besides that, I also got the Polot Hi-tec- coleto series for 4 colors.
And I didn't have any ideas to buy the color by Pentel Slicci, so I just bought the purple color to set up, so tomorrow what if I pass by the staionary store, I would buy another blue colors to set up. Should I try Zebra brand? I am condidering this brand now.

So only four pen holder could contain 15 colors inside, in this way I could save the space and reduce the weight of my luggage.
