rOtring Isograph Technical Drawing Pen College Set, (0.20, 0.30, 0.50 mm), Includes Pens, Pencil, Eraser, and More - Designed for Precision

I adore these technical pens. After doing endless research on whether or not these were compatible with Speedball Super Black, I decided to just get the cleaning kit too, and do my experiment. I'm pleasantly surprised to find that the Speedball ink doesn't dry or clog the pens at all, as long as I screw the caps back on after use. I went about 4 or 5 days without using the pen I put the Speedball Ink in and the only annoyance was a very small dot of ink that gathers on the nib that needs to be wiped. I also store them upright instead of laying them flat. The ink it comes with is also fantastic, waterproof on both smooth and textured surfaces such as cold press watercolor paper. They deliver the ink so smoothly and evenly, it's amazing! The very thin line from the .20 is just lovely! I thought it would be my least favorite of the three but I actually love it, and find myself wanting to put more tiny details into my drawing. $40 for a set of pens that will last you a lifetime with proper care is a great deal, I'm glad I got these! UPDATE: I went 3 WHOLE WEEKS without using the pen filled with Speedball Super Black, and no clogging whatsoever. Started writing immediately!

For the past 2 years I’ve wanted these pens and I’ve finally gotten them, my expectations for them were far exceeded by how great these pens really are. From reading the reviews of how scratchy and messy they are, I’ve found that the smaller the tip the more roughness you’ll get out of them, but even with the slightest pressure they flow so good with ink, so the lighter you press the smoother and less scratch you get. So far, my smallest, .25 is really smooth for me. The price is definitely worth it for these pens. The clean up is easy. They last years and years, so I’ve heard, all you’d have to buy is ink, which is super super cheap considering that’s all you really have to buy. I love the feel of the lines and I’m satisfied with the flow of ink, I would recommend making or buying a grip, since these pens aren’t very ergonomic and do hurt a lil after using for hours. These are now my favorite pens. I will defiantly be buying all the sizes as time passes. 10/10 would recommend if you want to save a ton of money in the long run. I’d also recommend getting a case for them as to keep them in good condition when you’re on the go. Thank you rotring for creating my perfect pen.

I love these pens they write beautifully.

Great set of pens to have for technical work. Unfortunately with the set having no front protection mine came in a bag and the compass attachment broke.

EXCELENTE

I love these. I draw a lot and needed a sturdy pen for line work and stippling and these have held up great! In this set you get a lot for your money!! the ink it comes with dries quick and doesn't smudge with watercolor, water base markers, or alcohol bases markers. it does fade a bit with heavy eraser. the smallest pen does leak a little on the cap so you might have to wipe it a bit. but that doesn't stop me from loving this. it could be just my pen too. im not mad!! they are comfortable to hold, and I do have small hands. I can't find anything bad ! ...... oh okay, they can be a little scratchy... but with a metal nib its to be expected!! LOVE LOVE LOVE LOVE!!

Excelentes mis plumas de dibujo Rotring, estoy muy contento!

These pens unlike Staedtler are not as sturdy(body- wise) but better than Koh-I-Noor pens, which I spent over a $100 on and they started falling apart in less than a few months usage with the slightest bumping. I've been drawing regularly with these, and even when I'm not working on a project, I'll 'walk them' to keep them working smoothly, these pens so far after a few months don't disappoint. There's definitely upkeep, not for ignoring so please use them even if it's just doodling a random line. It keeps the ink from clogging. I bought these because I go through disposable pens so much the costs add up. I don't mind the upkeep vs. the cost because these pens are worth it. However, if drawing is just a hobby, you might want to stay with disposable pens.

伝統を重んじるドイツ製のグラフィックペンです。私もかつて大学院生のときの修士論文でお世話になりました。グラフをこのペンの0.5ミリで描くのですが、直線がにじみ苦労しました。これは普通の定規はインクゲージというインクのにじみを防止するオフセットの付いた定規が必要なのですが知らないとは罪なこと。何度も書き直しました。見栄えはグラフ描画ソフトの比ではないです。圧巻の美しさです。これの0.3ミリ以下はインクが詰まりやすいかなと言う点が懸念されますが、使い方をきちんと学べば全く問題ないです。インクが出なくなったら、まずペン先をティッシュで拭う。これでも出ない場合は、インクタンクを手で温め、熱膨張によりインクを出させる。これでもダメな場合は、安全な場所でペンを振って、慣性力で出させる。後はこの複合をやればいいです。このように多少は手間も掛かりますが、これを使いこなし、美しいグラフィックを完成させた時の感慨はひと潮です。もちろん、私は、車のグラフィック・デザイン画を作成するのに利用させてもらっています。ドイツの伝統技術を使いこなすことに無常の喜びを感じるのは私だけでしょうか。

Ok, acquistato ad un prezzo ottimo rispetto al mercato

Excelente producto! Lo compré de regalo de cumpleaños para mi papá (es Ing Civil y dibuja muchos planos) y le encantó, dice que es una excelente herramienta de trabajo. Además llegó en perfecto estado, el empaque y todo bien.
