The Air-Tite album has padded black vinyl front and back covers with six clear top loading pages made to fit 400 series cards. We sell the cards separately so that you can pick out the ones that exactly meet your needs. We recommend the ones listed for most collectors, but you can choose any other 400 series cards that you want. The slipcover measures 6.5" x 6.5" x 2.25", so it fits in safe deposit boxes and other tight spots where a standard album won't fit. When you order the album, be sure to order the six 400 series cards to fill it up.
