washer plate would be one of the best storage object of seed phrase, but to keep it safe is anothet thing. Because you have to keep it where children will not reach and use it to play and lost the plates. So I will also advise to store the phrase in another object preferably copy out and safe it in place that is secured.
Now my question is when the seed phrase is written on the washers and when you place it in the washers stand or there about, and the when you want to use it, won't you forget the words in the sequentialal order? Because of thing I am trying to understand from the washer is the words are written and placed on the Bible randomly. Because one washer plate can contain two to three words or is it that one place for one won't?
