Improve your writing efficiency with the uni-ball Chroma Mechanical Pencil Starter Kit. The included mechanical pencils feature auto-advancing lead and shock-absorbing points to prevent frequent lead breakage as you write, draw, sketch, and doodle. Not only does each pencil provide continuous and seamless writing, but they also feature a hexagonal eraser with crisp points and edges for laser-like editing precision. The large twist-up eraser allows for extra do-overs! This mechanical pencil kit also includes 0.7mm lead refills and a side-click lead advance on each pencil so that you can continue your handwriting project with ease. The sleek, modern Chroma design comes in a range of expressive colors for a fun and colorful writing experience, whether you're pencil drawing, pencil sketching, outlining shapes, writing essays, taking notes, and more.
