This is a step forward in the safety- & inheritance-concept I am currently developing for Monero.
Admittedly, branding this with it’s own name might be a bit presumptuous, but heck … I enjoy presenting things in a pleasant manner.
The “Sealfodl” is really just a tightly-fit enclosure that draws its value from the possibility of telling if someone has gained access to its content and thus potentially compromised your secrets (keys, mnemonic, ssss, …).
A major part was finding a good and safe way to pause the print job and continue it from where it left off, allowing to hermetically seal the Billfodl in the process.
