Une des images a gauche dans la page de la description montre la clamp avec élastique. Plus they are wireless which is great. Worst pillow purchase ever. Does not hold up! This is true. To change that, go to settings > general > keyboards > hardware keyboards > caps lock switch to turn it off If youve read all the online reviews as I did, I cant encourage you more strongly to skip these and move to the next option on your list. They go to my ankles, I assume so I dont have a high chance of twisting them if I fell. so its a really big bag. So, please note, that the context of this review for use with a sony xperia 10 regular, not with any other device.
