I picked up this nice bluetooth keyboard the 3E neo recently. It's a japanese brand. It fold's into pocket size but feels so sturdy and the keys are the perfect size. So satisfying

The IC-BK20se from iClever does look very similar and might be available, but no guarantees. I decided to go with the japanese product because the marketing material seemed more polished. I had a look at the model with the trackpad but the keys were a little smaller. Bit too small.
