Where do you keep cold storage crypto?

I'm curious to know, where exactly do you keep your cryptocurrency in cold storage? Cold storage, as I understand, is a highly secure method of storing cryptocurrency offline to protect against cyber threats. But do you keep it at home, in a safety deposit box, or perhaps with a trusted third-party service? Can you elaborate on the specific measures you take to ensure the safety and security of your cold storage holdings? I'm eager to learn more about your strategies for safeguarding your cryptocurrency investments.
