Dunno about the cresent moon, but there's a brand called "Snarling Dogs Brain Picks" that have that same grippy pattern. I bought it for the cool metal box

but ended up loving the grip stuff. They only had 1.0 mm at the store....
Funny part is, I found out that's the same brand one of my guitarists uses.......cause they've got sweaty fingers too ! Now I gotta keep an eye on my picks before I'm down to none

Heyyy wait, then I can buy another cool tin......hrmmmmm
