How do I transfer KLAY to MetaMask?

Hello there, I'm curious about the process of transferring KLAY tokens to MetaMask. Could you please walk me through the steps involved in doing so? I'm particularly interested in knowing if there are any specific requirements or precautions I should be aware of before initiating the transfer. Additionally, is there a fee associated with the transfer, and if so, how is it calculated? I'd appreciate any insights you can provide to help me navigate this process smoothly.
