I used to give out laminated paper wallets with a sticker over the private key. It’s effective if you’re using an old-format P2PKH address but now I’d prefer to use an OpenDime or stamp a seed plate for long term security.
Discussion
What do you use the seed plate with? Hardware or software wallet?
You can use it with any BIP39 wallet but your strongest security will come from using a ColdCard or another bitcoin-only hardware device like Foundation Passport.
