Yubikey 5 NFC case for a keyring?

I need a durable Yubikey case that will stand up to dirt and keys. The "Switchblade" style cases will not work due to wear and tear from sand and keys. I live in a rural area and spend a lot of time outdoors working in a sandy and wet environment which is hard on everything (pocket knives need a lot of maintenance for example).

I am going to get a new 5C NFC version but, I need to get a good case first! I need something reasonable for my keychain which has way too many keys! 😉

I'm thinking Amazon but Ali Express is an option too. What are my better options?

Thanks!
