It isn't really important what other people think about your pen; it is YOUR pen & as PakMan says, it is important that it be pleasing to you. It would make me crazy & I collect Folk Art & appreciate the nuances that make a handmade piece unique. This pen was NOT handmade, but was from a production line & if offered to you as a choice, you would not have chosen it.
I filled today a pen, my first "Bespoke," purchase; which upon arrival from England, I immediately noticed the clip was a "bit off center," & despite the material, fittings I selected, a WONDERFUL customised nib, has always bothered me. The Company who made it went "out of business," shortly after I received the pen & I knew it would not be a situation that could be addressed. I will always suspect the "Bespoke offer," was tendered @ a time when the Company was perhaps "not doing normal business" & it would not have been addressed if returned overseas. It is the first thing I notice when I fill the pen, use it, uncap it, or see it in a pot of other pens. I suspect you will feel the same way about the irregularity of your pen's patterns & would be happier to have a different pen, that is more like the one you chose to purchase.
My Father & Grandfather were very "car proud," & both seldom were happy if their car needed body repair, if involved in an accident. They were NEITHER going to be happy with the repair & always claimed to notice the difference, trading the car for a newer model, despite the mileage. I am NOT the same way about a car, mine has been involved in two accidents; I was just grateful the repair was possible because the body style of my car, changed the year after my purchase & I like mine best. But I realise how they felt when I look @ my pen.
Besides, after your pen is replaced, just know you have given someone who prefers the unique character of your pen, an opportunity to purchase it!
