Viski5399 Angled Crystal Coupe Glasses, Stainless Steel, 7 Ounces, Silver

Why does the description on the top say pack of 4 which the price reflects and then the description says set of 2?

What is the dimension of the mouth of the glass?

What is the diameter of the base? I'm hoping it will fit in a hanging rack

Does the glass have a pulled stem, or can you feel a seam/edge along the length of the stem?
