My last order of grease pencils came in last week, and they're different from what I normally get. Our distributor had to change what they usually stocked because these new ones are apparently the only brand they can get anymore, and these are an absolute abomination. They fly right through the sharpener, the "lead" breaks and splinters and snaps with extremely minimal pressure, they're hard to mark with, and once you DO get the ball marked, you've gotta scrub pretty hard even using ball cleaner and a microfiber towel to get it off. These things SUCK. Got any good recommendations?
