Bought these on here… used once and then found out that wearables aren’t the best if you’re an undersupplier. Comes with everything pictures (minus two milk bags I used) “Everything you need for the 3.0 Willow pump system in excellent condition. Includes size 24mm containers and spill proof flanges for use with bags, 45 bags, and size 21 flanges. Includes an extra set of containers in size 24. Also in the set is a brand new, unused haakaa pump and stopper set.”
