Mid-century vintage pressed glass punch cups, sweet little old-fashioned cups like tiny mugs. They have a whirling star or pinwheel pattern.
These would be lovely candle holders for votive candles or tea lights, they're quite heavy, and sparkle beautifully with the pressed pattern, like crystal.
There's eighteen cups in this set. These measure about 2 1/4" tall, 3" across the rim, and hold about 4 ounces. All in very good condition without damage.
