Recommendation for long-term storage of graded blast white silver coins?

I asked two AI tools (ChatGPT and Claude) how best to store graded blast white silver coins over the long-term, so that they remain blast white. Both AI tools gave similar answers, emphasizing the need to limit environmental exposure (eg, humidity, exposure to chemical fumes, etc). Their answers were similar regardless of whether the coins are stored in a home safe, elsewhere within the home, or in a bank safe deposit box. Here is their recommendation.

Store the slabbed coin in a protector bag.
Store the bagged coin in an Intercept sleeve.
Store the Intercept sleeve in a box with a gasket seal (eg, a Pelican box, or something less expensive).
Throw a desiccant bag in the box, and change it periodically. Both AI tools recommended staying away from desiccant bags that change color, saying that the chemicals used to invoke the color change are potentially harmful to coins.

The AI recommendation seems like more due diligence that many will want to undertake (including me). But if you have some nice blast white or toned coins, and you want them to stay as they are, what do you do? Does the AI recommendation have merit? Thx.

Personally I store them In plastic protector bags so they don’t scratch but it limits the amount of air reaching my coins. Storing them in a wooden box as well. Nothing has deteriorated in the 5 years I have owned them. I want easy access to my coins to enjoy them. However if it was an expensive rare copper coin maybe I would think differently.

I use the Intercept Shield box designed to hold 50 slabs, but not the individual one slab Intercept shield holders. Maybe I should do both? Who knows? Regardless, keep in mind the maker of Intercept Shield says to replace their products after 10 years. That SHOULD be done!
