The crux with picture frames is that it is so damn annoying to change pictures. And when changing pictures, I have already cut my fingers half bloody on these impossible clamps and snap-on things!
The picture frame from 'Lehni' doesn't want to know anything about all that and offers absolutely stress-free picture changing and a great look at the same time. That's why the traditional Swiss company also calls the clever parts 'interchangeable frames', because pictures can be changed here quite simply: Simply pull the upper part of the frame made of sheet steel upwards, remove the hardboard with glass, insert the picture of your choice and then push the whole thing back together.
For you I have compiled some common formats.
