BLOT Mechanical Pencils 0.7 mm Medium Point, 2 Lead Pencil Grade, Built-in Eraser, 4 Assorted Warm Barrel Colors Mechanical Pencil Set - 24 Ct.

Never saw erasers that disappear so FAST. And, as an artist, I'm not grinding down on them or anything. But after a single use (erasing 4-5 words), you see a big chunk is gone from the side. After a 2nd similar use, you're left with about half the eraser left. It's weird! And it'll keep me from buying these pencils again. I'll find different mechanical pencils. OH!! And hate the fact that you can't twist or push or click the lead back down into the pencil to protect it from breaking. Once it's out, it's out. Too bad if you push out too much, or want to keep it from marking on your white comforter when you lay it down.

Purchased these to use in the wood shop and they are exactly what I wanted. Good product.
