Pentel Mechanical Pencil Lead, Ain Stein, 0.3mm, 2B (C273-2B)

Works well in the Pentel Orenz Nero pencil. Writes smoothly and is as dark as a traditional #2 pencil. You get a lot of lead per capsule too. The thinness is perfect for cursive writing. I will definitely be buying more when the time comes. Small warning to anyone unaware: 0.3mm lead is fragile and 2B lead is even more fragile than the HB lead which most people use in mechanical pencils, it will wear down faster, and it's more difficult to erase. Also, the container got me stopped at airport security once because the officer thought it was a vape, haha.

This has everything I want in .3 lead. Dark lines, erases well, long lasting and break resistant. They’re also a good price, what more can you ask

Quality I can and do count on.

I got this to refill a couple .3mm pencils I bought for my math classes. I suppose I'm a little compulsive about neatness in my math homework. This lead has really great (dark) color which makes writing small notation like exponents on college ruled paper a real pleasure. The only drawback is that this lead is VERY soft/delicate for such a small diameter and is probably be best suited to a mechanical pencil with very small lead advancement increments and auto-rotates the lead as you lift the pencil up from the paper. You'll probably go through these at twice the rate of a .5mm 2b, but that's because of how delicate the point is. If you're using this for actual drafting where the pencil is held perpendicular to the paper and used with a straight edge or shape, it'll last longer than hand writing where the pencil is at an angle to the paper and more prone to snapping if it's been advanced one click too far.

Nice leads, sturdy.

Smooth, strong lead; much better than regular Super Hi-Polymer lead from Pentel. Slightly less dark compared to that product line. Ain Stein 2B is less dark than Super Hi-Polymer B. Great for writing; however, I am still undecided on whether these are good for drawing. Graphite doesn't lay very evenly when layering and doesn't blend with regular graphite that well. It could be the additives or it could be my imagination.

The led works great, it looks darker and makes bold lines. It does break a little easier but it’s expected from a .3 mechanical pencil led. Met expectations.

I used to buy Uni leads for my detailed pencil portraits but decided to try these - now I won't go back. Much more break resistant at the .3mm size than anything else I've found.

It's really good. It doesn't break and is smooth. Very good for the price. And the lead is long lasting

👍

Ottimo rapporto qualità prezzo.

The Pentel Ain STEIN C273 0.3 mm HB leads are a great choice if you need very fine, precise lines for detailed writing or technical work. The 0.3 mm thickness allows for extremely accurate strokes, making them ideal for small handwriting, sketches, or drafting. ✔ Very smooth writing experience – The HB hardness provides a good balance between darkness and durability. ✔ Strong for 0.3 mm – Surprisingly resistant to breaking, even under moderate pressure. ✔ Clean and consistent lines – No scratching or uneven marks. ✔ Convenient pack size – 15 leads per box is practical and lasts a decent amount of time. ✖ More fragile than thicker leads – As expected with 0.3 mm, heavy-handed users may experience breakage. ✖ Not ideal for bold writing – The fine tip is great for detail but won’t give strong, dark lines like 0.5 mm or 0.7 mm. Overall, these leads deliver exactly what you would expect from Pentel’s Ain STEIN line: precision, reliability, and high quality. If you use a 0.3 mm mechanical pencil for detailed work, this is an excellent choice.

Perfect for the Pentel Orenz mechanical pencil which keeps them unbreakable!
