Manufacturer description

The ProtoArc XK01 gives you a genuine desktop keyboard layout in a bag-sized package: 105 keys with a full number pad, function row, and navigation cluster, all on 0.65in keycaps so your fingers land where muscle memory expects. Fold it along the internal aluminum hinges and it collapses to 8.46 x 4.68 x 0.78 in, small enough to sit beside a tablet in a laptop sleeve. Those hinges are tested for 10,000+ folds, and the no-clip design means you unfold and start typing instead of fiddling with latches. Bluetooth 5.1 pairs the XK01 with three devices at once, and a single button moves you…
