Mr. Pen- 0.7 mm Lead Refills for Mechanical Pencils, 480 pcs (120 per Tube), Black, 2B Graphite Lead, Standard Mechanical Pencil Refills for Drawing and Sketching

Just what I needed.

These were just what my son was looking for to fit his previous bought NicPro mechanical pencil set for school. They fit perfectly, great quality and durability. He also appreciate the handwritten thank you note. Would definitely buy again.

These leads are a good value for under $6 but are soft and brittle so probably not good for drawing. They are good for writing and drawing lines on Technical drawings.

Works as intended. Writes smoothly. Vibrant colors.

I can make my pencils colored pencils now... Sweet ..

I love the number of lead refills as well as all of the color assortment. I have not had any of these lads break on me and they do an excellent job in terms of coverage and visibility. I am very happy with these lead refills.

Exactly what I was looking for does the job?

Oh, these 0.7 #4 leads are great!!! I am learning a foreign language and like to write the questions and answers from my program down in pencil to study later. My problem was that the pencils I was trying to use were too light. I use pencils because I can erase mistakes easily. The #2 pencils I had to sharpen too often and the mechanical pencil leads were far too light. I found these #4 leads and hoped they would be better. Yes!!! They are awesome and you get so many for the price. They hold up to my abuse and are strong. Maybe it is the 0.7 size. Plus, they fit my Pen+Gear mechanical pencils. I will buy more of these leads later on this month to build up a large backlog. I plan to use the language program for a long time.
