Have you gone to Hobby Lobby & looked in the drafting section & the drawing section?

Finally got around to checking Hobby Lobby. They did not have replacement 2mm leads in HB. They did have a cheap 2mm leadholder that came with 12 different color leads. However, there is no labeling of the hardness of the leads. But for $2, I bought it anyway. They are definitely much softer than the 2H that came with the one I originally purchased. But they seem way to soft to only be HB. When I pulled it out of the box, it easily marked on my finger.
