Blackwing x Independent Bookstores 2024 is the 4th limited edition set to celebrate independent booksellers which Blackwing have been releasing since 2020. This year they've gone for a blue colour theme with gold detailing which is reminiscent of old leather bound classics. They contain the firm graphite which is the same as in the 602 pencil and roughly equivalent to a 2B, making it smooth to use and giving a solid dark line on the page.
