Reddit mentions of Paper Mate(R) Tuff Stuff Eraser Sticks, Pack Of 2

If anyone is curious about refill erasers like I was, the Sanford Tuff Stuff eraser sticks are the right diameter, and you can just use a razor to cut them to a desired length.

Now you're talking one of the biggest problems I always had as well! Drawing white hairs/details was easily one of my biggest roadblocks. I tried white pens and such, and personally didn't like it.

I 100% recommend a "Tuff Stuff" eraser stick. The stick itself is no different than any other mechanical eraser, but the eraser itself is a godsend. It is extremely durable and tough. I cut the end of it with scissors to create a sharp edge, and then I use it to eraser white lines into my graphite. It's best used on light graphite to get your white guidelines set, and then you darken the area around after drawing your white lines. Regular erasers sticks are generally no good because they're too soft. They just can't get the sharp, crisp erase lines like the tuff stuff ones do.

Unfortunately they aren't easy to find any more, and can be quite expensive now.

The stick itself I've seen range anywhere from $10-$100.. It's pretty ridiculous, you should definitely look around for awhile before you buy. I bought mine long ago for $8. The refills are what is really important though. The best deal I've found is here for 24 sticks: https://www.amazon.ca/Paper-Eraser-Holder-Refill-64818/dp/B00006IFAZ/ref=sr_1_1?s=office&ie=UTF8&qid=1469120190&sr=1-1&keywords=tuff+stuff+eraser

I couldn't recommend it enough, but again, it's personal preference =].
