Flexes are small, plastic hooks, thanks to which you can freely adjust the height of the curtain and eliminate any irregularities up to 6 cm in the vertical axis. An additional advantage is the ease of hanging the curtain on a curtain rod or KS rail and the possibility of washing the decoration with the hook. Undoubtedly, the biggest advantage is that the curtain on flexes always stays wavy. There are hooks every 10 cm of the curtain width.
