DelGuard Mechanical Pencil Eraser Refill, White, 5-Pack | Break-Resistant Lead, Double-Spring Protection, Compatible with DelGuard Mechanical Pencils, Long-Lasting (83225)

I'm a mechanical pencil freak. Have been since I was in grade school. I got all kinds of clutch pencils and mechanical pencils in my collection. I usually get a few unusual pencils a year, I decided to give this one a shot. Though, suffice to say, I'm a .9mm guy, it was a pencil I "gotta" have in my collection. It does hold up to it's name with it's name to claim. Up to 3 clicks, the lead will not break. A few times I got it up to 4 clicks and the lead didn't break. But with 1, 2, or 3 clicks, you can press really hard and it just retracts back in, then when you release, it pops back out. Pretty neat design if you ask me. Only downside is, there is too much plastic. I prefer metal pencils. Like out of aluminum or brass, made with metal components. There are only a few left that use all metal parts. But you are looking at spending some cash. However, it appears if the pencil is well made, and the components are engineered in such a way that it should last several years. Longer if only used at a desk. Zebra gives you extra pencil leads, in HB (#2) grade hardness. I did notice they seemed more like a H hardness, more than a HB. Maybe just a quality HB lead? Not sure. I'd have to do more analysis on the lead composition. Just by the faintness of how it was writing compared to my Pentel HB, and my Nano Dia HB leads of the same thickness. I have a feeling there is more clay in the lead making it stronger, more like in the middle ground of H and HB. I need to try some of my Pentel colored leads in it. They are a LOT more brittle than regular pencil lead. Curious to see if the DelGuard system will protect against broken colored leads. As that was one of the reasons I was looking into this pencil. Whenever I get around to it, I'll come back and report my findings. All in all, it's a great pencil for the money. It goes up similar to my Mitsubishi/Uni Kuru Toga with the rotating lead mechanism.

The mechanical pencils won't let you down. The spring means you can press down harder without fear of the lead breaking and they are light enough to not cause fatigue but sturdy and simple enough to be used by a frequent note taker.

Great product. The pencil for these replacements and these erasers are impossible to find in person where I live so it’s nice to be able to order them straight to my door

I’m a hamfisted, mechanical pencil snob. I love this pencil. No more broken lead! The only thing that could make it better, is if they combined it with the one that rotates the lead every time it lifts off the paper so it’s always on the sharp part.

The "secret" to non-breakable leads here is not just the leads, but the supporting mechanism. It works quite well! Instead of rigidly holding the lead, this tip allows sideways movement in 360 degrees so it is far less likely to break the leads when writing. The leads themselves are also more durable. I know this from my other use, which is marking and layout for woodworking. The grain of most woods tends to grab any lead and break it. That is especially a problem when using INCRA rulers. INCRA's small holes require a .05 MM lead, which is why I tried these. I'm happy to report that these work very well with INCRA rulers and are less prone to breakage, even when marking porous grained woods like OAK. Are they truly "Un-breakable?" Not quite. You still can't bear down on the lead like an angry gorilla. But assuming you have some modicum of civility, these are noticeably better than standard leads, and the pencil mechanism is decent for normal writing too. The springiness of the tip is still stiff enough to write legibly, but it feels "spongy" if you press hard. Verdict? I like the leads very much and use them in other mech-pencils for woodworking marking and layout with INRCA rulers. For that alone, the product is worth the cost for me. For writing? So long as you write on a smooth surface and don't press too hard, they work well and may help those with heavy handed calligraphy.

I've been sold on Zebra products for years and love them to this day. Zebra is the best brand of mechanical pencils, lead refills, and replacement erasers. There is none better for the quality you get. I'd guarantee I've probably saved a fortune on mechanical pencils over the years by buying Zebra because they do not break near as easily as the cheaper brands.

The lead is fine but I really like the round tubes that fit nicely in the slots of my pen cases. It’s nice to be able to carry refills on-the-go without needing a separate pouch or having the lead container floating around loose in my bag.

works great

INCREÍBLE. JAJAJA nunca en mi vida pensé estar tan feliz con un lapicero, cabe aclarar que sirve como un lapicero normal, pero este tiene la capacidad de ayudar a que personas que presionamos mucho el lapicero al escribir o dibujar a que las puntillas o minas no se rompa tan fácilmente, si logré romperla pero fue por que saqué la mina 3 veces cosa que el producto dice que ya no es capaz de proteger, aun así al momento de inclinar ayuda mucho a que no se rompa ya que tiene como una manga que sale justo cuando siente que la presión va a romper la mina , de igual manera de forma vertical como que mete la mina y ya no se rompe, cosa que con mi otro lapicero barato no podía hacer, la he estado usando para tomar apuntes y hacer uno que otro dibujo y de verdad que se siente increíble saber que tienes algo así en la mano además de que en el color blanco te deja ver el resorte y su mecanismos internos, ¿la volvería a comprar? SÍ, la calidad de el plástico es buena , no cruje ni nada, lo único es que quizás vea en el largo plazo es si se raya y ya no se ve tan bien el resorte y demás.

great product the only issue was a delay in delivery

Really does work unless you press down at a hard angle and then the lead will snap, but I'm prone to pressing very hard when I write and I thought mechanical pencils would never be a thing I could use, and I really hate sharpening wood pencils because I want the point FINE all the time and it's a waste to sharpen them every minute or so. I would break leads constantly on other 0.7 mechanicals. This pencil really works for me and the hand-feel is OK but there is no cushion for your fingers so it isn't the best for really long time writing and for those who like the rubber grips. I do wish it had a rubbery grip for the finger area. The eraser is super small and won't last long but never does in these kind of pens. Don't rely on it.

The order came way earlier than it was supposed to which was a nice surprise and the amount of leads in the package was generous. I am very impressed and this was money extremely well spent. Would recommend to anyone!

It's a cheap and reliable little mechanical pencil. It writes fine, and it's actually really sturdy, like it a feels of well construction. I can see myself using this for a long time.
