Ethan's canteen , the Staff's logo is visible on the canteen.
Ethan Rom carried a canteen while he was spending time with Claire after having kidnapped her. When Claire was woozy after being injected by Ethan, he offered it to her to drink from and she said the liquid inside tasted sour. Ethan made it clear that he did not notice this. ("Maternity Leave")
While overseeing Kate and Sawyer working at the quarry, Juliet had a similar, if not the same, canteen. She offered it to Sawyer when he noticed her drinking from it, but he rebelliously poured it out as she was watching. ("The Glass Ballerina")

- The one difference is that the logo on the Staff station black with the staff graphic in red while the logo on Ethan's canteen is white with the staff graphic still in red.
