Pencils are usually the first implements we use to make marks. There are multiple things about these mark makers that make them super special. One pencil can draw a line 35 miles long! They have been used in space, they can write underwater. The marks they make can be easily erased. We could go on. Show your love for pencils by getting one of these for your tote bag or even your pencil case!
