This is a set of four vintage Corning Pyrex Corelle mugs featuring a Holly Days pattern, perfect for Christmas. Made of white milk glass with a glossy finish, each mug has a 9 oz capacity and a round shape with a handle. They are dishwasher safe but should be hand washed. The mugs are from the 1970s and have a festive design, making them a charming addition to holiday gatherings.

Excellent vintage condition with no flaws noted.
