I had searched a long time to find curtains in grey and yellow.  This feel like satin and do have a sheen to them.  They arrived quickly with no damage.  These have a dark grey metal grommet.  Easy to install.  The only negative is that I with there was a longer size.  I want the curtain to kiss the floor and these are about 3" too short.

Pros: Love the colors
Cons: Length
