Hiboom 24 Pieces 2.8mm HB Refill for Carpenter Pencil, Study Long Lasting Pencil for Mechanical Pencil Woodworking Construction (Black)

Good quality, white lead marks well on most textured surfaces , but marks poorly on very smooth surfaces.

Love having plenty of spares in my toolbox. Works great and they are pretty sturdy, but not brittle. Carpentry, stone and tile work - beats sharpening the old wooden pencils.

Super convenient, especially for construction workers. I can’t tell you how convenient it is that I don’t have to sit there and sharpen It and not to mention how thick the lead is so it doesn’t break so easily it’s not so brittle and frail

like that I can mark on dark wood with these white pencil refills, however, they do require going over the same spot a couple of times to make a bright enough line.

These work perfectly in my construction pencil and the price is way better than the manufacturer’s.

My husband is an electrician and I got these to go with the pencil he uses everyday. He has nothing but great things to say about this product.

Works great in my "X" pencil

These leads have become a daily part of my work! I brought the pencils about a year ago and have used them every since!
