Mostly okay

I can agree with the other review in part. I use these pencils (0.35, 0.5, 0.7 in the school as well as 0.7 and 1.0 at work as a carpenter for scribing) regularly.

In my opinion, they are from the thickness 0.5 for the price not at all that bad. From 0.5 onwards, faces never actually break off in my case.

But !!!!!!!!

The 0.35 he can confidently enter into the barrel pencils. Because breaks the air from even the simple press. Is a time near the end and the next should be pushed even jamming happy times together both in mechanics and then there's a lot of small items. I have several of them, yet often sit in front of a drawing and can use any, because they are all jammed or empty, or both. That is super frustrating.

I get you now (if I still get a) a Rotring 600. Those things are simply not beat (at least the old) !!

Three stars anyway for decent mechanical pencils with a larger diameter air
