Paper wallets are used for gifts and for storage when you want to move to a country or other item, but they are not suitable as a way to store all of your savings.
You can buy a phone at a much cheaper price than device wallets and convert it to a solid device.
You can also use an old computer and turn it into secure hardware.
You can try USB and open source OS.
Yes it can be a gift, but why exactly woudl you want to carry it on you when moving to a country? Why not post it here or sent by email or whatever..... What exactly will you do about it?
