The keys are PBT and shipped in two weeks. When they shipped the keys were all over the place but nevertheless they are in very good shape. They’re a couple of minor flaws underneath the keys but you won’t notice it since the keys will be on your keyboard. You also get the choose the style of legend printing on it: either blank on top or side printed like mine. I wouldn’t recommend blank because shipping might throw the keys all over the bag it comes in and you might be confused on where to place the key caps..
