Instead of traditional lead, the nib of this infinity pencil is made from a metallic alloy. It writes just like a regular pencil, and can be erased like a normal pencil line would be. However, it takes many thousands of uses before becoming blunt. The long working life, coupled with its bamboo barrel construction, makes it a more sustainable writing instrument. The shorter length of this pencil makes it suitable for golf card scoring or for jotting down quick notes.
