Matyz Glass Breastmilk Storage Containers, 4 Pack, 6 oz Bottle, Fit with Spectra Medela Avent Pump - Wide Mouth Breastmilk Collection and Storage Bottle with Lids - No BPA (2 Green & 2 Blue Lids)

You can use these bottles (Matyz) to pump into from the spectra and we figured out that the lansinoh nipples (which are recommended widely by LCs and pass the triangle test) fit into these bottles and collars. So sometimes in the middle of the night, I’ll pump into the Matyz bottle, slap a nipple on, and then I don’t have to go downstairs lol No silicone option though
