How to obtain KWD?

Could you please elaborate on the process of acquiring KWD, or the Kuwaiti Dinar? I understand it's the official currency of Kuwait, but I'm curious about the specific steps one would need to take to obtain it. Do I need to visit a bank or financial institution? Are there any online services that allow for the purchase of KWD? Additionally, are there any fees or restrictions I should be aware of when acquiring this currency? Thank you for your assistance in clarifying this matter.
