These hold backs look as pictured; however, they are not sturdy.  The curtains I use them for are very light weight, so I think they will work.  I would not recommend these for a weighty curtain.  The metal is so weak/ bendable that I could warp their form by apply too much pressure in drawing my curtains back.   I am very careful in draping curtains behind them for fear of warping or bending their shape.  

Pros: They look are pictured.  Easy to install.
Cons: Light weight/ flimsy
