Please choose the earrings (titanium post) and screw spring earrings (alloy plated) from the product specifications. Length (total length) about 4.5 cm The hydrangea petals are made of resin and four petals are combined to make a flower. A lump contains about 20 flowers. I also used gem-quality peridot and amethyst to represent the drops of rain. The back catch of the pierced earrings is cotton pearl. I made the earrings look like back catches.
