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.
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.

Watch out! The "B" lead is a scam, as it charges way too much for just a single container of lead. You don't get the full box like you do for the other lead types.Published 27 days ago by M. Brady
