512 on two of them, one is 128 and im not sure about the others and yes i have 4 of them with only two slots on the bottom of them and i miss counted there is 10 of them
i think i could send them all for around $5 and i will make sure that for for the winning bidder i ship them safely and make sure they do not get broken i have bought an item on here before and recieved it broken because of the poor packing job
