ACME Studio make a wonderful and unusual range of writing instruments, with a strong emphasis on design and flexibility. They have worked with many of the world's greatest designers and architects. Each pen is either designed by a renowned designer, or, in cases where the designer or architect is no longer with us, is based on a design by them.
The interchangeable grip sections on their design rollerballs mean that not only can you change to a different type of grip (rubber, knurled metal, chrome), but you can change the pen to become a fountain pen or a capacitive stylus. By just changing the refill, it can become a ballpoint or a felt tip.
The combination of quality construction and playfully fun design makes the Crayon and Number 2 pens perfect gifts - a perfect way to make someone smile each time they use it - even if that person is you!
