Agreed! That is just beautiful work and design.
If I may make a suggestion - Two options on this. When I have tried designs in segments, matching two ends with the same design - in some cases enhance each other, and in other cases, the same design distracts. (I had an ugly pen to prove it.
) My suggestion is if you have an extra tube, make two or three variations of the other end - solid or small horizontal designs instead of verticals.
My point is, sometimes designs on both ends enhance and sometimes they don't. You don't know until you try. That is too good of a design to leave with one pen option.
