• Double-walled PVC-free plastic is durable and reliable with a completely leak-proof closure to ensure long term storage is safe.
• The bag has an area to write when the milk was expressed so you know exactly how long you have stored it
• Sealed from air and moisture to ensure milk nutrients are retained
