Nice

This pencil lead writes smoothly on any type of paper, however it's not recommended for high quality papers of 70 GSM and above. The lead tends to get used up pretty fast on high quality paper and feels no different from 2B leads. This 4B lead shines when used with notebooks with inexpensive low GSM papers. THat kind of paper is not fountain pen friendly, it's prone to feathering and ghosting. Even gel ink ball point pens create ghosting and feathering. This 4B lead is ideal for that kind of paper. You get a nice dark line and there is no need to worry about feathering and ghosting.

Quality of leads is amazing and smoothness also great. But the packaging really needs to be improve, they just put the address sticker on the lead box and it really difficult to remove it which is really bad.

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!

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.

Qualidade e bom preço.

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.
