This is a disposable baby bottle. I purchased it around January 2025 for a disaster preparedness kit, but fortunately, I didn't need to use it, so I'm putting it up for sale. I opened the outer box of the Steri-bottle to check the contents, but the inner bag is unopened. I will also include the more compact chu-bo! and a sample Kaneson breast milk storage bag (unopened, but the exterior has some creases. It's a plastic bag, so the product itself should be fine, but please consider it as a bonus. If you don't want it, please send me a message on the transaction screen.)
