Kenko KN-80 Name Card Holder

I was stressed out making my hubbys stuffs in order, especially with name cards. Hes been receiving a lot of name cards from his companys suppliers. Every time a supplier pays a visit to his company, he would be given their name cards. Eventually these name cards are piled up, and I cant stand having these messes. One day I was shopping for papers in a stationery store and I found this item, name card holder by Kenko, model KN-80. Its small-sized, and can hold up to 80 name cards. This looks like a photo album, actually. The inside background is black, and the plastic that we slip the name card into is not so thick. But its a clear plastic, so the name card can be clearly seen (I looked at other brands and they had somewhat blur plastic which made it quite difficult to see the name card). I bought three of this kind at once, and am actually looking for a bigger card holder that can hold more than 80, because Im running out of space now and the name cards keep coming and coming. I wanted to get rid some of the old name cards but my hubby wouldnt allow me to do so. I asked the store keeper where I used to buy them and she said they ran out of stocks for now. So I might go to other store to find these.
