4 Cartier Crystal Glass Sherry, Wine, and 10 similar items

This is a set of 4 Cartier "crystal" glass sherry, cordial, liqueur, wine glasses in a red hinged box. The glasses are in the Cartier CTC7 pattern, a cut arched design with a smooth stem. Each glass is approximately 6" tall. On the underside of the base is an etched "Cartier". When I purchased these, I was told that they are "crystal", however, I have not had them tested for lead content, density. or reflective index. The glasses have never been used. They nest in a red box in fitted blue velvet with a white satin like top lining. The lining has "Cartier" in gold. I checked the glasses and there are no chips, cracks, scratches, hazing, or discoloration. There are occasional small bubbles in the crystal. The top of the red box has some discoloration. See Photos. I purchased these at the Cartier 5th Avenue store in the mid-1980s. They have been packed away ever since. I am downsizing and am selling most everything. Non-smoking household.
