Approximately 8.3 x 8.3 x 4 cm About 300g The opening is narrow, and the part that holds water is also small. It's not suitable for flowers from a florist, unless it's for very small roadside flowers... like a speedwell or shepherd's purse. It's heavy for its size, so it might be good as a stand for dried flowers ^_^ The artificial hydrangea is used as a reference.
