This is a folding Bluetooth keyboard from iClever. I'm selling it because I've upgraded to a newer model. The mechanical folding mechanism is very cool. It's lightweight at only 185g and a compact tri-fold keyboard that fits in your pocket! The use of aluminum material eliminates flex and wobble during typing, providing a comfortable typing feel like a laptop. Simply opening it turns it on/off, making on-the-go work stress-free. Recommended for building a comfortable mobile environment with smartphones and more! The case cover also serves as a stand for smartphones and tablets. The condition is good, but there are some minor scratches from use. Please check the images.
