Zebra Pen DelGuard Lead Refills 0.5mm HB, Break-Resistant Graphite for Mechanical Pencils, Smooth Writing, Compatible with DelGuard Pencil, 1-Pack, 12 Lead Refills Included (89881)

My wife apparently can tell the difference b/t mechanical pencil lead makers and NEEDS zebra's kind. The normal rectangular packs of them are all almost gone, there's even one on a 2 month journey to my house from China in case these didn't work, but luckily THEY DO! And they're CHEAP. So best lead, best price, less plastic than before. 5 stars.

Very good product. I’ve used them for decades.

Once you get used to the mechanism this pencil is a great writer and it is very difficult but not impossible to break leads.

Fits my Special Edition Horoscope Zebra Delguard Mechanical Pencil. I love that I got them for a great price!

The grip is good, it's sturdy and I like fine lines.

I tried another 0.5 mm lead and could not get it to work. I had to use more expensive lead of the same brand as the pen. It is still worth it - nice pencil and the leads don't break easily.

Could not find this lead locally for my mechanical pencil. Was surprised to find it here. Glad I took the time to look, and now I have the lead I need.

I wouldn't buy anything else for .5mm lead
