I was buying in bulk, but I've finally stopped breastfeeding, so I'm wondering if anyone else would like to use this. Of course, it's unopened. The expiration date is April 2027. I'm sorry, but I can't offer a discount due to shipping costs. Instant purchase is also OK! I will wrap it in two layers of bubble wrap and send it in a cardboard box (I don't have one the exact size, so it will be a box that has been cut and modified). Please feel free to ask if you have any questions!
