Organize your home with Haakaa’s Sealed Glass Storage Jars! This set comes with four 4 oz/120 ml and two 7 oz/200 ml durable borosilicate glass jars, each with its own airtight and leakproof 100% silicone lid.
Borosilicate glass is extremely durable as it is able to withstand extreme and shock temperatures, which means our jars are perfectly safe in both freezers and boiling water. The silicone lids seal the jars tightly, keeping your contents fresher for longer. They’re perfect in the kitchen for safely storing baby food, ingredients, spices and herbs – you can even use them in the bathroom for things like toothpaste tablets, cotton buds and makeup wipes! Our Sealed Glass Storage Jar Set is so versatile and handy and is perfect for every eco-friendly home.

Borosilicate glass resists temperature shock, so jars go from freezer to warm water without cracking. Clear glass also makes it easy to identify contents at a glance.

Each jar includes a 100% food-grade silicone lid that seals tightly to keep liquids and purees secure. The lids are flexible for easy opening and cleaning while still preventing spills.

The set includes four 4 oz jars and two 7 oz jars, ideal for single-serving purees, snacks, and portioned ingredients. Compact, stackable jars save space in the fridge and diaper bag.
Pick jars that match how you store, freeze, and reheat baby food for safe, low-waste feeding.
- Match your portions: Choose jar sizes that fit typical serving amounts so you only thaw or reheat what you need.
- Freezer friendly: If you plan to freeze purees, look for durable glass and tight lids; leave headspace for expansion and chill flat before stacking.
- Reheating safely: Remove the silicone lid before microwaving, or warm jars in a bowl of hot water to avoid thermal shock and splatter.
- Easy to clean: Avoid bleach-based cleaners, use soft brushes or sponges, and sterilize by boiling 2 to 3 minutes when needed.
- Think about use: For on-the-go, pick compact, leak-resistant jars; for pantry storage, choose stackable jars with clear labels.
Are these jars safe for breast milk?
Yes. The borosilicate glass and food-grade silicone lids are suitable for storing breast milk. Follow safe breast milk storage guidelines, chill or freeze promptly, and sterilize jars before first use.
Can I put these jars in the freezer and reheat later?
Yes. The glass is freezer-safe, but leave headspace when freezing and let frozen jars thaw in the fridge. Remove the silicone lid before microwaving or warm the jar gently in hot water.
Are the lids truly leakproof for liquids in a diaper bag?
The silicone lids seal tightly and prevent most leaks when upright. For long trips or rough handling, double-check the lid condition and pack upright to minimize risk.
How should I clean and sterilize the jars?
Wash before and after each use with warm soapy water or in the dishwasher. Do not use bleach-based cleaners; to sterilize boil the jars for 2 to 3 minutes and use only soft brushes or sponges.
What are your shipping and returns policies?
We ship from a US warehouse, and US orders over $100 qualify for free shipping. Moogco offers 30-day returns, and our human customer support team can help with questions or returns.
