Dr. Brown's™ Muttermilch-Sammelflaschen

These fit right onto my pump flanges so there's zero transferring spills, and the measurement lines are actually easy to read even at 6am. I've frozen a whole stash in these and the caps never leaked a drop.

The twist-on caps seal so tightly that I’ve never had a single drop leak in the fridge, even when I lay them sideways. They’re incredibly easy to clean with the wide mouth, which makes my middle-of-the-night pumping sessions a lot less tedious.

These fit my pump perfectly, so milk goes straight from the flange to the fridge without a single transfer. The screw-on caps seal tight enough that I've never had a leak, even lying flat in the diaper bag.
