dockblocks are little modular USB-C docks. Each one has something useful on the side, like an ethernet port or a bunch of type-A sockets, or high quality analogue audio. There are two USB-C sockets (one on each end) to plug into the host machine, power, or other USB-C devices. They stick together with magnets so you can neatly chain a bunch of them without any extra wires. Unless you want wires, in which case use a wire to chain them instead.

They are reversible, so the ports can face front or back. They stick. They don’t suck.
