Instant purchase is OK. This is a set of ASTRO Yoon Sanha trading cards. I am selling these items because I am no longer collecting ASTRO merchandise. Individual sales are possible, but buying the set is a much better deal (I would prefer someone who can buy the whole set). After opening, I put the cards in sleeves and stored them in a trading card file. If you have any questions, please ask in the comments. Thank you.
