Zebra Mechanical Pencil, Del Guard, 0.3mm, Luminou Pink (P-MA85-LMP)...

I like that it takes a lot to break the lead, it feels nice, easy to write with, and the size of the lines are sharp, and the pen looks great.

Great item good stability and lead does not break easily

The Zebra Del Guard mechanical pencil is declined to save you graphite, by making git harder to break. The mechanism holds up well (even when the rest doesn't) enduring drops well with no bending. One of my complaints with the mechanism is that it enduces wobble, especially in notebooks, from added resistance. I feel it unnecessary for a 0.7 mm pencil, and the graphite doesn't break all that easy. On a 0.5, it is useful but not to such a degree as with 0.3. The mechanism had a lead sleeve that, when the graphite bends, it engages a taper, thrusting the sleeve outwards. It also has a spring on the whole lead mechanism to dampen vertical force. All that added together means that it is extremely difficult to break the graphite, which would be the case if the body werent as atrocious as it is. It is all plastic with ridges on the end as a "grip", which made it hard to hold comfortably, as you have to choke the pencil to keep it from sliding in your fingers. The ridging just makes marks in my fingers, and hurts them over time. The rest is also plastic, despite its brushed appearance. The body bends more than I would like, causing the graphite to break. Also what is holding the graphite guard, is also made of plastic, with no lubercation, thus slowly eroding away. At one point, with the 0.5 model had it in my pocket, and sat down. It broke in half. I would recommend you buy the delguard LX, which solves most of my complaints. In conclusion, the delguard is a good showcase of the design, but is not much more. I would not use this as a daily driver (I would use my r0tring 800+ instead) but it is a well designed mechanism.

This is the mechanical lead pencil - PERFECTED. Somehow, Japanese engineers who had nothing better to do found a way to counter the pressure from your hand to the lead & paper and eliminate it - thus completely solving the problem of leads constantly breaking in mechanical pencils. It works like a 100% effective shock absorber on car, using springs inside the body. We saw this little miracle on an NHK/PBS TV show about the resurgence of hand-written letters and notes in Japan (a counter-reaction to impersonal electronic social media and email.) IT ACTUALLY WORKS !!!! Buy it while it is available. I purchased the .3mm, .5mm, and .7 mm versions (going from fine point to wide point.) I would recommend the .7mm model for a wider script, but they are work flawlessly and precisely as advertised.
