PSI only has thepencil in 24k gold, brushed satin, and black Ti. I won't use 24k of bushed satin as the platings wear too quickly. The black Ti is too expensive for this person.
AZSil only has pencils that match the 8mm euros, and she is adamant that she doesn't want the double twist.
Now I don't know if there is a big difference in size between the 8mm and 7mm euros, but there is a difference in the centerband. If someone can confirm how they match up in size, I might be able to say "the centerband difference is so you can tell them apart at a glance"
