Can a Robinson Zip Coin Case be used as a wallet?

I'm curious, can you elaborate on the functionality of a Robinson Zip Coin Case? Specifically, is it designed to securely store and carry cryptocurrency tokens, or is it more suited for traditional physical coins and notes? If it can indeed serve as a wallet for digital assets, how does it interface with various blockchain networks and ensure the safety of one's crypto holdings? On the other hand, if it's primarily intended for physical currency, what features does it offer that make it an attractive option compared to traditional wallets?
