Are these type of things normally purple? I don't have one so I wouldn't know but I've seen clarinets pull a string with a peice of cloth on them through the main peice.
they come in all sorts of colors but what ever instrument you play dont do it
dont ever buy one, they obsorbe the spit for a short while then next time you clean it it just goes right back into your instrument, i had one for my band flute and it made my pads sticky
