We've got odd and ends of washers lying around but strictly speaking no, as we really have just got a box of bits. They do come complete with the braided line kits though.
Thing is I don't think we've got the right ones for everything, it really is just a box of a load of random copper washers. I needed one the other day and it took me about 20 mins of fishing to find one washer the right size.
