Well in my case I would want a cold storage wallet that works with multiple currencies… but not sure about my associate. I think they only have BTC.
It depends on your expertise level, and if you want multiple currencies, or at BTC Only.
If you want something simple with multiple currencies do Trezor ( https://trezor.io/ )
If you want something simple with Bitcoin only Foundation ( https://foundation.xyz/).
If you're more advanced Bitcoin Only I would say ( https://seedsigner.com/ ).
If you're advanced, and want Multiple Currencies then I would recommend getting a PC or Mobile Phone, and not connecting them to the internet, use Cold Storage Air-Gap methods, or Generate a Paper Wallet on an offline device.

I recommend the Trezor, or The Air gapped cold storage set up.
Both guides below follow the same general set of principles, and can be replicated for most other cryptocurrencies.
