6PCS Breastmilk Storage Bottle, BPA Free Wide-Neck Spectra Bottles for Pumping, Storage Collection Baby Bottles for Fridge & Momcozy Breast Milk Cooler, Breastfeeding Bottle, 10 oz

I got a 3D printed case that perfectly fits the parts for my wearables that I quite like. I actually got 2 since I have two sets of pump parts. I wash them along with my pump parts. https://www.etsy.com/listing/4361672867/3d-printed-breast-pump-case-eufy-s1-pro There are other vendors out there of course, but this is specifically who I got mine from. Unless you plan on doing the big pitcher method, I also recommend getting some larger milk measuring containers for storage. I am donating my excess breast milk and the bank requested that any donated milk be frozen after 24 hours instead of 4 days, so a big pitcher would be overkill.I got these since they have mL and ounce lines. https://a.co/d/07maGGqg
