Thank you for viewing. This is a medication bottle I purchased because my child couldn't drink from a cup when entering daycare, and I thought using a dropper would be too much trouble for the teachers. I have stored it after washing. Fortunately, my child was able to drink from a cup without needing it, so I am selling it. I tested it with water during washing, and it didn't leak, and it seems easy to use. Boiling sterilization should be within 60 seconds.
