Aktiv cards

hello
I have the opportunity to buy aktiv cards (majik 140) occasion with a good price (http://www.lejonklou.com/forum/viewtopic.php?t=1854). it is a second hand and the seller sells it because he doesn't want to go active.he send me photo, it s seems to be in good conditions, but he doesn't have the original package and the anti static bag.
so i wonder if the lack of protection anti static can damage aktiv cards.
I have another question, on the back side of the cards it s written akurat (small) , and below there is a sticker with chakt 53 .... And majik 140 bass-médium.......

Thanks for your response
