Okay, I won't keep you in suspense. It's obvious to me, but maybe it's just my OCD. The blank is pearlized green, and is dark green on two sides, while the pearlization shows on the opposite two sides. Normally when I assemble a pen with a blank like this, I orient the clip over one of the dark sides, so the pearlization shows at 90 degrees to the clip. The way I assembled this one, the clip covers one of the pearlization areas. I wasn't paying attention when I pressed the clip assembly into the body. Unfortunately, I can't see any way of dissassembling it. So I'll have to live with it this way.
Oh, and thank you everyone for the compliments!
