This is a beautiful set of 4 hand-blown mugs in the pulegoso style. Each is ombre starting with white at the bottom and gradually changing to dark brown at the rim. Pontil mark on bottom on each indicating hand blown. The handles are a thick applied glass.
1 has a piece of the applied glass handle missing but is still fully functional (pictured.)
1 has what looks like an internal crack (pictured) but you cannot feel it inside or outside of the glass.
