The most common form is a hardware wallet, a small device that signs transactions without ever exposing your private key to a connected computer. An offline paper or metal backup of a seed phrase is another form.
Cold storage trades a little convenience for a lot of security and is the usual choice for holdings you do not need to touch often. Its counterpart is a "hot" wallet, which stays connected to the internet for everyday use and is therefore more exposed.

Cold Storage — часто задаваемые вопросы
Is cold storage worth it for small amounts?
For small, actively-used balances the friction may not be worth it; cold storage earns its keep as holdings grow.
Can cold storage still be lost?
Yes, if you lose both the device and the seed-phrase backup, so secure, redundant backups matter.
