Review on High-Speed Waterproof 64GB USB 3.0 Flash Drive Keychain - Moreslan Silver by Adam Ross

I use this as a medical warning label. I wear it on a chain around my neck. I am allergic to some medications and take several maintenance medications. That's too much for a traditional engraved label. It also includes a will and custody documents for two people that I am responsible for. It has no moving parts, the clip is durable and waterproof. Perfect for my needs!
