I have an original Lead's Crayon Sharpener so I measured the ridges.

They are 1.27mm or 0.05" wide and 0.50mm, or 0.02" high.

Very subtle ridges.

It would be a easier to see if I took it out of the package...but I do want to do that.

The only place it says "leads" is on the bottom. It says, "A Leads Sweete Product".
