Approx size is 22cm x 23.5cm x 3cm (I'll also include a tennents lager keyring with this)
The cable has a switch to turn on/off, cable is pretty short so a power bank would be best and is what i use, or a nearby USB plug or an extender will be needed.
Everything is from a pet & smoke-free home, all these items are made at home by me on a 3D Printer.
Due to the nature of 3D printing technology, slight imperfections may appear. These minor defects include lines and bumps, which, if examined are visible.
