I used this for about two weeks to measure breast milk volume. I used it with a bath towel on top, so it's in like-new, very clean condition. I will wipe it down with a disinfectant wipe before sending it, just to be safe. Purchase date: April 2025 Operation confirmed Instruction manual included Will ship in the original box. There are traces of a shipping label on the box, but the main unit is clean. I will leave the batteries in so you can use it right away.
