Well...this isn't really an opinion but i need help here. I got in my silver brian boyle prospect auto jersey and need to know what size magnetic to get. Before i just took one from another card in my pc that didnt really need the magnetic and it fits snugly to the point where if you shake the case the card doesnt move. But now i don't have any more magnetics to use and i am having my friend pick one up for me cause I am really busy and cant get to my shop for a while(and hes going soon)....so after all that rambling, What size magnetic holder should my friend get for my superlative prospect auto jersey? Thanks
