These beautiful vintage curtain tiebacks are made of pressed opalescent glass in a flower shape. They still have their original pewter posts. I have two pair of these. They do not match exactly but are close enough that they could be used together. The opalescent glass is just lovely. The price listed is for one pair.
They do have some issues - one of each pair has a large chip as can be seen in the photos. Because the chip takes out a section between the petals of the flower shape it is not that noticeable - it almost looks like it was designed that way. The screw portion of one of the stems is also somewhat bent.
