son...go to "avatar" then click the "change avatar items" button, on the left side there are items in your bag/items you use in equipments,the fragments,etc. when you click those jimmys, there is a load closet in the middle (of course I wont explain this one cause there is and arrow button saying restore and change) just put the little jimmys you want to convert with your avatar coupon and presto...you have a converted avatar item...
