Judge small enamel roaster x2 new chipped at end (Westbury Fields BS9)

Two black enamel roasters from Judge, 28cm by 22cm by 4cm deep. Brand new, both arrived with small chips in the enamel around the holes, see photos. It will not affect day to day usage but they will go rusty in time. I wanted to put them in the dishwasher but know that the dishwasher tablets will make them go rusty really quickly. If anyone wants to hand-wash them and see how long they last, you are very welcome. It seems a shame just to throw them out.
