0.5 mm Pencil Lead Refills (Total 240 leads) 2B Hi-Polymer Premium Strong Dark Soft Smooth Lead Refills Suitable For All Standard Types of 0.5mm Mechanical Pencils by Buncho (Pack of 10)

I understand that this is the first review so I'll try to give as much information as possible:1: I am not an artist, and use the leads for my everyday lecture notes which I'm having a lot. So, I've tried many different leads recently and this one is..cheap!! It's a really good quality by itself, if you also add the price on the top of it, then you can't beat it.pros:1. the leads cam 2B so the information was correct.2. the darkness is very good. It is really dark and smooth3. the pencils are 70mm in length instead of traditional 60, which means the nearly 10mm leftovers that almost all pencils leave is being used in a more sustainable way. I like it.4. I just finished writing a page, no breakage so far.cons1. when you write, tiny particles of the lead accumulate near the tip of the lead. but it does not create problems. at least for writing.2. the packaging was a disaster. I had ordered this with a pencil. they came in one package, the thin layer of the plastic package of these leads was damaged so in the large amazon envelope I found a lot of lead tubes mixed up with a pencil.3. some of the leads were broken in their tubes (in total, not more than 10).So, overall, would I recommend this product? definitely yes!

A good one

Best mechanical lead I’ve ever used. Really dark and smooth to write with

For the price it breaks way to much for no reason within my drafting pencil itself. The only benefit is they give you a significant amount. Again it doesn’t break on the paper but within my M301
