Cumplen lo que prometen. Buena calidad

Not sure what it was, but this lead kept breaking so I had to return it. Also, it sounded "squeaky" when writing

When I first saw the price of these leads compared to locally available brands, I almost didn't buy it. But you definitely get what you pay for. This is the smoothest, darkest (for the grade), and all around best lead I have ever drawn with. Now that I've tried it, I don't want to put anything else in my pencils.

Very nice lead! Velvety smooth flow when writing and darker than others I’ve use. Other leads leave a sheen or shine with their markings, but not this one. As such it’s easier to read in some artificial lights. I use this in a Rotring 600 and find that it advances more smoothly and efficiently in that pencil’s mechanism than any other lead I’ve tried.

First time I used something with such a soft grade of lead. It's very smooth, almost like writing on silk. Put this in my Pentel Sharp, and it works without a single issue. However, this is way too expensive in North America, especially in small amounts. If you like this lead, find multiple packs. Overall, its smooth, dark, and durable, wonderful pencil lead.
