Pentel Ain Stein 0.5Mm Mechanical Pencil Lead | Lead of Grade 4B | Smooth & Not Scratchy | Easy to Insert Inside The Pencil | Pack of 40 Pcs (C275-4B), Black

Excellent quality leads. Almost no smudging. Smooth. But feels like a slightly lighter shade compared to other standard leads in the market.. (searching/comparing online and buying recommended..)

Genuinely the best one at this price pint for such quality. very durable and rich darkness color!

Very good

This is very good quality

I actually bought these .5 mm, 4B leads by mistake -- I thought I was buying .7 mm. However it has turned out to be one of those really lucky purchases, because the leads are just excellent. Drawing is a smooth and enjoyable experience with them, and I don't even feel I'm using a .5 mechanical pencil, because the 4B softness of the lead translates to a darker, denser line than you normally get with this gauge. You don't have to be a famous physicist to reap the benefits. Highly recommended!

It is really good, I love the quality of the lead well.

I ordered 5 but received only 1 while ordering from sekaido_Japan seller be mindful as my experience with them was bad. The main quality of this lead is its tensile strength being "H" its very dull to the eyes when you write with. It has not snapped like the budget leads I have been using. Compared with Camlin and Faber castle this is very unique in the way it feels when you place it between your thumb and index finger and pushing it to snap. Its very difficult to get this lead to snap and when paired with a quality mechanical pencil like uni kurutoga advance upgrade that I used to test this lead with. The writing process becomes seamless as there is no constant snapping of the lead while you write. I generally put around 7 N of pressure when I write. Which is high enough for any leads to snap except this one. The storage box is made of plastic making it very lightweight but it will shatter If you sit on it or drop it or step on it. Its construction reminds me of the old school iPod as its very sleek and angular and has a certain charm of a feel in the hand . The cap being textured gives a good grip and makes it easy to rotate and open to access the leads stored inside. The rotation of the cap is resistive and genuinely becomes a fun fidget toy for me to play with in the class as at every rotation it provides a strange tactile feedback that is wonderful to feel. When you hand it over to your friends they will try to pull the cap. Please ask them to rotate. All of this for 120? It's worth it if you ask me.

Nice

鉛筆の4Bには負けますが 色も濃く柔らかく書きやすかった！

It is getting harder to find hard pencil leads. these are great for technical drawings.

These pencil leads are quite nice. A little pricey, but you absolutely get what you pay for. Creamy smooth writing feel, and they definitely don't break as easily as less expensive leads. These are for sure my new favourite for my P205's.

Even though I also like to write with 0.5 2B (B is too hard), which already means I'm a fan of the softer side, having found Pentel Ain Stein 0.5 4B leads was a dream come true. I know they are great for nuances - light or dramatic - in drawing, but writing is definitely why I use mechanical pencils, so bear in mind that this review is from someone who mainly writes (taking notes in class, making notes, solving exercises, eventually drawing graphics, journaling, ...). They are smooth to the point of turning writing into a gentle high velocity (if this makes and sense), as we so need on uni classes. The trace is easy to erase and it never ever scratches paper. Even in Bible paper, which is uncoated and ultra-thin - which says it all. Writing with these leads it's like floating on paper to the pace we decide. Writing with Pentel Ain Stein 0.5 4B leads is simply a pleasure. They turn the tiredness of a long writing session into something less tiring to fingers and wrists, thus, more enjoyable and more focused. I use them with Pentel Graphgear 1000 and Pilot Dr Grip. Although PentelG1000 has the ideal (imo) lead sleeve because it's long and prevents breakage, Pilot Dr Grip (Play Border and Pilot Dr. Grip HDGL-50R have no such long sleeve and, yet, they don't break the leads. However, they easily break with Rotring Tikki and classic Pentels (sorry, Pentel, love Pentel, your classics, but your wonder 0.5 4B demands a more refined Pentel...). At least, that's my experience. I Believe it's pointless to use these leads with Kuru Toga mech pencils, because if you're on the softer side, you don't want the lead to be sharp all the time. The tube is easy to work with and there's no danger of Breaking a lead while taking it out. The packaging could be more proper to the size of the tubes, but, at least, it arrived in the expected time.

でも文房具屋に行けば普通に売ってるので引きこもり用かな
