What size are these hats, will they fit adults?

Do these have a thick cloth rim or is it thin white cloth over cardboard?

What is the circumference of these 'one size fits most adults' hats? tia

2 pack of 12; how many does that mean? 24? I'm confused about what 6 pack 12 means verses 2 pack of 12 since the 6 pack costs less.
