I was looking for artificial orchids in the stores and they didn't look real enough and were expensive (around $40).
I got 2 orchids from House of Silk Flowers and they look great and real (white and lavender, which looks better in person than here on the picture). The flowers can be adjust a bit.
To my surprise the shipping price was the same for 2 flowers as for one, and I couldn't resist to get two colors (I was debating which one to get).
My slight complaint is that top arm could be longer like it is in a real orchids, but I am happy with price and quality and would buy it again.
