A Razertip exclusive! Curved speartips allow you to reach into areas otherwise unreachable. The point of the tip overhangs the pen barrel, allowing the hot point to contact the surface even in very tight areas. Sliding the foam grip back on the pen will extend your reach. Most people are amazed at how effective the #12 tips are at reaching into undercuts and other hard to-access places. Can also be used for general fine detail.
