A very close up photo of the fingertips of Sini's right hand. There are, indeed, interesting tiny callouses and the skin of her pointer finger looks absolutely shredded like it's been experiencing minute damage for several weeks, healing over again and again, now a sort of pink fingertip with plates of dry skin attempting to flake off, but also polished to a high shine by constant contact. It's not a huge amount of wear, but it's on a very very small area.
