See the title.
I just read a thread recommending someone to get a stampable cold wallet from a crypto wallet site to store their recovery phrase. While I agree a solid flame-proof steel plate is optimal for recovery seed storage the cost was $$$$. The prices on the product was a $100+ for a single 10 x 6 steel plate with a few lines on it. You also have to do the hard work and stamp it (the stamping kit cost extra) or pay extra for the slidable letter tiles.
You can get a 10×6 steel plate from https://www.onlinemetals.com/ for like $3 (+ $10 for shipping) then purchase a stamp kit from amazon for $15. It doesn’t have fancy lines on it but I’m sure you can get a line stamp for like $2 somewhere.
Finally, you save yourself from providing a crypto company access to your personal information (name, phone number, address).
