I recently obtained a P1135N, and surprisingly, there was a difference in the structure around the tip. I can’t completely rule out the possibility that it’s a minor change depending on the manufacturing period, but I’m sharing this for reference.

From our master’s book…
The P1135N is a match for the RK10 Rolling Writer Pens in matching colors. It was available with the matching RK10 in the Roller Pen Set PRSK10.
The “N” version of the P1135 is about 8.6mm shorter in the body than the regular P1135.
I suspect that this version was made to match the size of the RK10 Rolling Writer when it is capped, so that they would look the same size when sold in a set. When posted, the RK10 is the same size as the P1135.
