Champagne bowl glasses in emerald green color, they are estimated from the 1950-60s

Incredibly beautiful champagne bowl glasses in emerald green color, they are estimated from the 1950-60s. They are so beautiful and decorative, handmade and we think they are italian (from empoli glass), but we can't say for sure. They measure approx. 12, 5 cm in height and 11, 5 cm in diameter. They weigh between 162 and 181 grams each (they are mouth-blown/handmade, so they vary minimally in weight, expression, etc.) The price is for all 4 pieces together. Packed securely and shipped with insurance. Shipping eu 15 €. Shipping uk 30 €. Shipping rest of the world 55 €.
