It's better to be more friendly to your pen ✒️ when it comes to crypto wallets than your keyboard, I have never lost my funds from any wallet that I wrote down it's recovery seeds with my hand, it's always those that I type using a keyboard, or trying to import wallet into another wallet.
Only if you write it down correctly. If you only write it down but don't test that what you wrote is correct, zero mistake by try to recover with it, you will not be able to recover your wallet later. This is when you still lose your coin even you did wrote seeds down on paper.
Furthermore, paper is vulnerable with water, fire, physical damages, though you must save it in a secured and very safe places.
