Can I send Optimism to MetaMask?

Excuse me, I'm a bit confused about the compatibility between Optimism and MetaMask. Could you clarify for me if it's possible to send Optimism tokens directly to a MetaMask wallet? I've heard that Optimism operates on a different network, so I'm wondering if there are any specific steps or considerations I need to take to ensure a successful transfer. Additionally, are there any fees associated with this type of transfer, and if so, how do they compare to regular Ethereum transactions? Thank you for your help!
