For every set you select you will receive 10 snapbuds, of which you only may use 4 to 5 snapbuds on your earbuds depending on which configuration you choose. 
 
They are made from heavy duty polycarbonate plastic wrapped around a super magnet.  Each snapbud measures approximately 1cm in diameter and weighs 2.5 grams.  
 
You will also receive 2 snapbuds anchors that are placed on the auxilary cord.  You only need one anchor of course, but this allows for you to have an extra.
