Glass or crystal flower candle holders

Here are two very beautiful glass or crystal candlesticks, beautifully transparent, in the shape of flowers with 6 curved petals. They do not have a label but are strictly identical to others (seen on the internet) which still have the "hand-made" label. They would date from the 60s or 70s, without certainty however. The interior receptacle has a two-tiered shape made to receive both long candles (at the bottom) and candles with a larger diameter or tea lights (upper part). They are in very good condition, no cracks or chips, few or no scratches, just two or three small chips under the base but which seem to me to be "defects" of the original shaping, because very smooth and completely invisible. They measure 12.5 cm in diameter, 6.5 cm in height.
