I use a Mycelium Entropy device for all of my items.
https://mycelium.com/mycelium-entropy.html I also buy them as part of my Bitcoin history collectable items
If you cannot find one....and they are impossible to find...do the following...
Use a Trezor. Reset the device....get a new seed created and use that to place under the Holo and use the corresponding public address for the loading part.
You can then reset and do as many times as needed to get as many new addresses as you want made.
And it goes without saying...use the following as well .
Air gapped computer
Air gapped printer
Water proof paper
https://bitcointalk.org/index.php?topic=5296179.0 I also recommend if you use any other device instead of just a qr code for priv key also print a second one with the alphanumeric key as well. Just my two Satoshi...that's what i always do anyway.
Hope that helps.
