Elevate your storage and gifting with Mcupper 4 oz Glass Mason Jars

Designed for clarity and durability, these 4 oz mason jars are crafted from 100% food-grade glass. They’re BPA-free and lead-free, giving you a transparent container that shows off the contents while remaining robust for everyday use. The jars are refrigerator-safe, microwave-safe when the lid is removed, and dishwasher-safe, making cleanup and reuse straightforward. For freezer storage, you can chill liquids up to a practical limit, helping you preserve flavors without worry about breakage or leaks.

With a regular mouth of 2.59 inches, these 1/4 pint jars balance easy filling and clean pouring, whether you’re portioning fruits, herbs, sauces, or dried snacks. The true workhorse here is the airtight seal: silver lids paired with a silicone gasket on each jar create a reliable barrier against moisture and air, helping preserve freshness and minimize spills during transport or storage.

Everything you get in the complete set

• 40 glass jars with 40 silver lids and bands
• 48 round stickers + 48 oval stickers for labeling
• 50 tags and 2 hemp cords for personalized notes
• 1 sponge and 1 sponge brush for easy cleaning

Beyond canning, these jars shine in craft spaces, kitchens, and event planning. Use them for jams, honey, spices, or dried snacks, and then repurpose them as charming vases, candle holders, or decorative containers for weddings and parties. The compact size and crystal-clear glass make it easy to mix-and-match with your décor while keeping contents visible at a glance.

Practical uses and care

• Store preserves, sauces, and small-batch goodies with confidence thanks to an airtight seal.
• Organize pantry shelves, craft supplies, or sewing notions in a uniform, space-saving system.
• Gift-ready packaging: personalize each jar with stickers, tags, and twine for seasonal favors or favors for weddings and baby showers.

To keep jars looking their best, wash with the included sponge and air-dry, or place in the dishwasher with lids removed. For microwave use, heat without the lids, and for freezing, limit liquids to safe levels as recommended. This set is designed to adapt to your kitchen routines, celebrations, and creative projects without compromising on safety or quality.
