>>54290232BCW sells them with a screw down version and they are by far my favorite type of slab. I use them all the time because I have autism and have been keeping cards in my pocket since I was a boy. The magnet ones tend to slide open and then they bend the card if I use them that way so I used to simply tape them sealed but these things keep them closed and safe from absolutely everything except dust and water. Good thing sealable sleeves also exist now.
