I'm not too particular on storage methods. I keep everything locked away in a fireproof safe, but I sort everything together. I keep the foreign circulated in an old 2x2 binder, with everything else stored in small stackable bins. I definitely recommend keeping a couple silica gel canisters: https://www.amazon.com/Dry-Packs-Indicating-Aluminum-Dehumidifying-Canister/dp/B0025OO8DO/ref=asc_df_B0025OO8DO/?tag=hyprod-20&linkCode=df0&hvadid=167119222542&hvpos=&hvnetw=g&hvrand=1548238473629712802&hvpone=&hvptwo=&...
You could try a silica gel dry pack? I use them in my safe & in my pelican case that stores my Valve Index VR. They are rechargable. https://www.amazon.com/dp/B0025OO8DO/ref=cm_sw_r_cp_apa_fabc_C13VDVSJEMKB1CJABZ3K?_encoding=UTF8&psc=1

These are reusable. When they are saturated, toss them in the oven for a few hours to dry them back out.
Even if I were agreeable with the concept, I'd just leave my razor on a $5 silica gel canister...
I use this. Its reusable and convenient.
