I've been disappointed with how easily my .5mm leads break with my Alvin Draftmatic when I'm sketching big or bold. Wanted a thicker lead so that I could use 2B without having to deal with constant breaks. This pencil is a great compromise, with 1.3mm leadIt weighs nothing - like a feather. Took a while to get used to, but I like it now. Feels great in the hand, nice and chonky, and I haven't had a lead break yet. 1.3mm is fat and sturdy, yet not so big you need to sharpen it. Big pencil, big lines. The tip retracts inside for protection.The eraser is refillable with the June Gold retractable 12 pack, just cut them in half. I don't usually like plasticky things, but this is the exception. Bought the mega pack of Bild 2B leads and I'm all set.
