I would not recommend these mechanical pencils at all. When you begin to write the lead immediately breaks. I have used other brands that withstand constant use. I use a mechanical pencil 9 hours a day in my job and these have been a real letdown . One positive is the fine lead. It’s perfect and does not smear
STAPLES® NO. 2 MECHANICAL PENCILS FINE 0.5MM ASSORTED 12PK . The pencil lead breaks easily which makes it difficult to write with. Would not recommend.
Staples brand mechanical pencils works well. The tips are adequate as well as the writing. I use them all day during a 10 hour shift to make marks initial and write dollar amounts. With that I need to retract often. So far they last a pretty long time. Also I love the variety of colors in the box.
