Ive got a nice little array lined up at the moment.
I got a livestrong band fron New York last month, and a couple of normal reebok 50 cent "can't knock the hustle" bands (non-charity)
I also have a green "Save Darfur" band to stop the bloodshed in the african country.
I only wear the livestrong (as i feel very strong about cancer reasearch, as i have lost many of my family members to cancer) and the blue reebok band, as i like the colour! I wish i could give a better/deeper explanation for that one, but i cant, i just like the blue
