This is an authentic pre-owned vintage 5-piece cordial glass set from the "Collection of Birds" series by Hoya Japan. These elegant liqueur glasses feature beautiful, high-fidelity nature illustrations of forest birds set against a soft frosted finish. Each cordial glass stands approximately 3-1/8 inches tall and holds roughly 2 to 3 ounces, designed specifically for serving liqueurs or after-dinner spirits. This specific boxed collection includes the Common Redpoll, Varied Tit, Siberian Rubythroat, Long-tailed Rosefinch, and the Daurian Redstart. As a pre-owned vintage item, the set is in excellent condition with no chips, cracks, or fading to the detailed bird graphics. The set comes in its original Hoya Japan "Cordial Glass Collection" gift box. This is a sophisticated and rare find for collectors of Hoya Japan or those who appreciate fine avian-themed miniature glassware.
