18 Ounce Drinking Mug, Set of 4 Moscow Mule Hammered Copper

which is better lined or unlined?

Do these come over with the shot glasses and straws as shown in the picture?

What's the diameter of the opening and how tall are they?

I saw a photo from another seller where each mug comes in a black pouch. Do these come that way? I want to purchase as gift. Thank you.
