## Description

Durable Mechanical Pencil lead

Review: Lead Size - Lead held together well, product matched description and I am I artist, lead seems well crafted and well worth the cost, and very much convient, considering there isn't a local place to get these because of the 0.3 size
Review: I wish that I were writing this review with these leads! - Pentel Ain Stein Mechanical Pencil Lead, 0.3mm OK, so I prefer to write w poly leads and mech pencils rather than wood pencils...mostly. I have been using Pentel HB leads, and was marginally OK with them - BECAUSE I use 0.3 mm, and that is simply more fragile than 0.5 mm by a big margin. I saw some reviews of this lead and some other newer lead compositions, and figured for a few bucks, why not give them a shot? These leads REALLY are smoother, blacker, and stronger than my former HB leads. I had quite a bit of writing to do today - equations, mostly, and the start and stop of the writing in the equations often (grin) lead to lead breakage - so I tried this lead in 3 pencils: a Uni Kuru Toga, a Staedler regulator, and my favorite, a rotring Tikky II 0.35. Not one glitch in 3 pages covered in equations. Very sharp lines, and dark. Much improved viewing. The crowning glory are the Tikky I & II. I really like these pencils...been using for, oh, I dunno, a few decades. Can't get them any more. The smoothness is noticeable to anyone who writes regularly. I'm fine with the reduced feedback, with the blacker images and stronger lead. I am grateful that these lead companies continue to develop this technology. Now what to do with several boxes of

Great quality lead. I use it in my Pentel Graphgear 1000 and it has never broken while writing. It writes very smooth and always maintains optimal surface contact with the paper.
