I used this occasionally as I had an oversupply of breast milk, though I didn't use it often. It comes with a sterilizing case, so it's ready to use immediately. I plan to include items that fit in the sterilizing case when shipping. If you'd like, I can also include a Medela sterilizing bag, which is convenient for when you travel, so please let me know.
