Pentel Super Hi-Polymer Lead Refill 0.7 mm Medium, HB
Pentel Super Hi-Polymer Lead
Pentel first developed Hi-Polymer lead in 1960. Super Hi-Polymer lead is the perfect balance of dark, strong, smooth and uniform, which is why it remains the #1 selling lead in the world.
Pentel Super Hi-Polymer Lead is extremely durable lead that is ideal for high-pressure applications. Independent testing has shown that our lead can withstand up to 123.9 grams of pressure before it will break.
The average human hair is 1,000,000 angstroms in diameter, while the typical lead microspore is only 10 angstroms in diameter. However, Pentel Super Hi- Polymer Lead is just 1 angstrom in diameter. The smaller the microspore, the easier the lead adheres to the surface of the paper for smoother writing.
The way lead is produced has a lot to do with how well it will perform. Lead with too many gaps is prone to break. Lead with too many tight spots will create excess friction and reduce smoothness. Pentel Super Hi-Polymer Lead has an extremely low variance for increased durability and more consistent lines.
Each piece of lead is equivalent to a typical woodcase pencil. Pentel Super Hi- Polymer Lead can write 617 feet per inch of lead.
Pentel Super Hi-Polymer Lead is available in a variety of hardness ranging from 4B (softest) to 6H (hardest). The softer the lead, the darker the imprint, or line produced when writing. HB lead is similar to the lead found in a #2 pencil and is guaranteed to scan on all standardized tests.
Lead Diameter and Line Width
Pentel Super Hi-Polymer Lead is available in diameters from 0.3 millimeter up to 0.9 millimeter. 0.3 millimeter lead produces extra-fine lines ideal for small details. 0.5 millimeter lead produces fine lines great for accounting and general writing. 0.7 millimeter lead is the most commonly used size that is perfect for students and everyday use. 0.9 millimeter lead produces a bold line and works well for those that write with a lot of pressure or have limited fine-motor skills.

Here's a list of lead grades from firm (lighter writing) to soft (darker writing):
4H - 3H - 2H - H - F - HB - B - 2B - 3B - 4B
There are others but these are more commonly seen ones. Artists would normally be more inclined to go after the softer leads for fill and the harder leads for early sketching.
For standard writing purposes I use HB-Grade which as you can see is pretty much middle of the line, but F-Grade lead is only very slightly harder and lighter so the end result is just about the same.
Good luck with your choice, and I hope this review helped you in some way.
The lead write very smoothly and softly and never seems to break on me. It is also dark enough for my liking and can be used on scantrons in school. Other leads I have tries are brittle and snap and squeak when they write but this lead does none of that. It's not that good for drawing because it's a little harder so you should go for a softer lead but it's perfect for writing long essays. It doesn't smear when I write and erases cleanly. The container is easy to open by sliding it to the right. It never slips and has all the lead fall out. It's a great price online!
If you found my review helpful, please vote it as "helpful". Thank you!
So I decided to buy more on Amazon which usually offers good deals. And the ones in Amazon were the same products but much cheaper the time I bought them - less than $1/tube. And the shipment was fast. I am very satisfied with this purchase and they are sufficient for my following entire year's use.

Good price, good quality, good product. Of course it's good--it's Pentel!Published 10 days ago by K9Jackson
Thus far, thus good. I have a Graphgear 1000 and these leads work just fine. Way better than the thinner leads I've used for over a decade, just go ahead and get the thicker ones.Published 10 days ago by Chronic Mashedtater
