Organize your home with Haakaa’s Sealed Glass Storage Jars! This set comes with six durable 4 oz/120 ml borosilicate glass jars, each with its own airtight and leakproof 100% silicone lid.

The silicone lids seal the jars tightly, keeping your contents fresher for longer.

Made from durable borosilicate glass, these jars resist thermal shock and handle extreme temperatures. That durability makes them safe for freezer storage and brief boiling sterilization, so they work for baby food and pantry staples.

The 4 oz size is perfectly portioned for baby food, snacks, and small treats, and the compact jars fit easily in a diaper bag. Use them for on-the-go snacks, picnic portions, or to pack small servings for daycare.

Each jar comes with a 100% silicone lid that seals tightly to keep contents fresher for longer. The lids are BPA, PVC and phthalate free, and are safe to use in dishwashers, microwave sterilizers, and boiling water.
Pick jars that match how you plan to use them, from portion size to cleaning needs.
- Choose capacity: Smaller jars like 4 oz are ideal for single servings, baby food, and snacks, while larger projects need bigger containers.
- Check lid material: Silicone lids offer flexible, airtight seals and are easier to clean than certain plastics, just replace if damaged.
- Think temperature needs: If you plan to freeze or sterilize, choose borosilicate glass which handles thermal changes better than ordinary glass.
- Plan for portability: If jars will travel in a bag, pick sizes and lids that seal tightly and sit upright to avoid leaks.
- Consider cleaning: Look for dishwasher safe parts and avoid containers that require harsh cleaners or hard scourers that can scratch surfaces.
What size are these jars?
Each jar is 4 oz, which is 120 ml. That size works well for baby food portions, snacks, and small pantry items.
Are the lids really leakproof?
Yes, the silicone lids form an airtight, leakproof seal when closed correctly. Check lids regularly and replace them if you see any damage.
Can I freeze or boil these jars?
Yes, the borosilicate glass withstands extreme temperatures so the jars are freezer safe and can be sterilized by boiling for 2 to 3 minutes. Do not pour boiling liquids directly into the jars.
Are they safe in the dishwasher or microwave sterilizers?
Yes, the jars and silicone lids are safe in dishwashers and microwave sterilizers, and the glass tolerates boiling water for sterilization.
How should I clean and care for them?
Wash before and after each use with a soft sponge or soft bristle brush and avoid bleach based cleaners. Inspect for chips or cracks and replace if damaged.
What are your shipping and return policies?
We ship from a US warehouse, and US orders over $100 qualify for free shipping. We offer 30 day returns and human customer support if you need help.
