What should I do? I would like to sit in the evening with a mug of black coffee, but on a wide windowsill, so that outside the window there are pines and the moon is all over the sky. Yes, so that the windows are warm from some kind of oak. But no. We have to be content with plastic. Oh well. The main thing is that they did well, they even open and, more importantly, close. It doesn't blow. Thanks for the good work. I'll save up for oak ones. And you can also read books in the panel.
