These are hard rubber, minus the bakelite plug (first on the left in the line-up)

All are functional, all have some marks and signs of usage. They were used in a shop so they do have some marks. See pictures for more details, please. You get the six seen in the first picture and those six are shown in the rest of the pictures from different angles. Thanks and happy shopping. Keep in mind, some of these old splitters have the same size left and right prong holes rather than the one larger/one smaller plug entry point set-up.
