It's just they look rubbery. Like there made from rubber. I know that when they do any type of show or anything with drums or anything music like they edit it so you won't hear the real sound with the better music. So I know that when Animal would drum he's not using real drum sticks there rubber lookin. I'm trying my best to make some for my puppets to use (if I ever can) when I do live shows. So I need some help. Here's my solution. I was thinking of using those old eraser sticks but make them longer.
