It is necessary to specify some moments which many people are still confusing.
Our tokens are not in MEW or Metamask or any other "wallet", and even in the fat core wallet MIST they do not lie too.
Tokens and coins are in the Ethereum network but so-called "wallet" only give us access to the addresses which we have private keys from.
In other words, any wallet is just a program interface by means we operate with contents of the addresses which we have our private keys. And these interfaces can be called somehow: Mist, MEW, Jaxx, Coinomi, Ledger, Trezor, KeepKey, Metamask... etc.
The same is fair also for any other blockchains with their coins/tokens.
