true cold storage : any pen drive with tails os with encrypted persistent storage on an offline device (disable wifi/bt in the bios), view wallet only on line & sign your tx offline.
The seed phrase is stored in the offline device? What happens if a hacker get physical access to the pc ?
good luck to him to decrypt the persistent storage & then to find your wallet password before you recover your funds with your backups (you need to have no matter which kind of storage you use & you want them encrypted as well). nb : if using tails on pendrive he needs to get physical access to the pen drive not the pc, otherwise you use tails on virtual machine on the offline machine then the hacker also have to know you keep wallet on that VM before figuring out the different passphrases.
& it's not the seed, it is the private keys (that you encrypt with password to open your wallet & sign tx) that are stored.
the seed you get when you create your wallet offline, you make backups of them, you don't need to keep copy of them in the cold wallet. as long as the pendrive works you don't need the seed. you can backup your pendrive to avoid having to import from seed; when one pendrive fails you use the backup & buy a new one to have a new backup.
