The Milk Stork International Freeze & Check cooler is your go-to for checking breast milk as luggage while keeping it frozen for up to 96 hours. No dry ice, no stress.

🌍 Why It’s a Travel Game-Changer

• 🧊 Stays frozen for up to 96 hours
  Powered by high-performance vacuum-insulated panels (no buttons, no plugs).

• 📦 Holds up to 90 oz.(capacity established using 6oz bags of milk frozen flat in Lansinoh bags)
  Depending on your bag type + how you freeze it (pro tip: freeze flat for max space).

• ✈️ Check it like luggage
  Comes with a travel duffel and luggage tag so you’re good to go.

• 📏 Size: 12” x 8” x 10” — compact, but mighty.

📦 What You’ll Get

Your Freeze & Check cooler kit includes:

• Milk storage bags

• Tamper-proof stickers (for each bag)

• Circular exterior seals*

• Duffel travel bag

• Luggage tag

FYI: Airport security might break the outer seals if they need to inspect the contents — totally normal! But your bags will still be sealed.

✈️ Heads up: Airlines might charge a baggage fee. Call ahead and check.

💡 Smart Packing Tips

• Freeze milk flat (trust us — you'll fit way more).

• Avoid Willow/Kiinde bags if you’re tight on space.

• Cooler kicks into action automatically. No button-pushing needed.

📦 Shipping to Your International Destination

We’ve got you.

• 🚚 Shipped via FedEx International Priority

• ⏳ Order at least 7 business days before you need it

• 📬 Call your hotel/destination first to make sure they can accept your package

✍️ Customs might ask for a copy of your passport for clearance. If this is needed, FedEx will contact you directly. If they are unable to reach you, Milk Stork’s Customer Care team will also attempt to get in touch.

🛫 Taking It Home

• Cooler fits in the duffel we send — just check it like any other bag.

🚨 One Last Thing: Security Rules Vary

Airport Security Considerations:
Policies on checking breast milk as luggage vary by country and may be inconsistently enforced. Milk Stork cannot guarantee universal compliance with all international airport and airline policies.
