Hey guys,

So we have some multi-sig wallets for which I own one key and some other folks in my family own rest.
I wanted to keep the coins secured and store the keys away from each other such that it is weatherproof and you have to break it to see the paper key.

The key can be seed to Ledger.

I was considering sealing the paper in epoxy and add a paint layer which you have to scratch.
If there is already some solution then please guide me.
