Stylast black brush: missing now days.. Why? I like using the black brush

Stylast USED to come with a little black plastic brush with a small round flat clump of carbon fiber like bristles, to brush off the stylus. The OLD DAYS.. Now. no brush, no mention of the brush, But the Stylast website does still tell you how to use it!! (in the FAQ)                               
Anyone know why it vanished? Or how I can find one (several, a pile) of the brushes?
