Candy and edibles makers standardize their packaging with 24-packs, reducing packaging prep time. Resin artists store pigments, UV resins, and additives where child-resistant certification matters for household safety. Craft supply repackagers buy in bulk and fill these for resale. Diamond painters store bulk drill containers.

They absorb odors, degrade under heat, and look cheaper at retail. Glass jars cost more initially but appear professional, last indefinitely, and signal premium quality. Buying individual retail jars one-by-one costs 2-3x more per unit than buying a 24-pack. Mason-style jars with standard screw lids don't include child-resistant features, so you'd need to buy CR lids separately and verify they fit - this pack comes ready to use.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eAre these lids truly child-resistant, or just a screw-cap?\u003c\/h3\u003e\u003cp\u003eThe lids are certified ASTM D3475 child-resistant. Meaning they require a two-handed motion to open and shouldn't yield to single-handed effort by a child. They're not just a screw-cap. The push-and-turn mechanism is the certified design, not grip strength alone.\u003c\/p\u003e\n\n\u003ch3\u003eCan I put these jars in the dishwasher?\u003c\/h3\u003e\n\u003cp\u003eYes, the glass jars are dishwasher-safe on the top rack. Hand-wash the lids, as the gasket liner can degrade with repeated hot cycles. Air-dry lids completely before reusing to prevent mold.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's the shelf life of the airtight seal?\u003c\/h3\u003e\n\u003cp\u003eThe gasket lasts indefinitely if kept dry and not exposed to extreme heat. Once you open a jar, the gasket compresses slightly each time you reseal it. Most users report the seal remains functional for 200+ open-and-close cycles before the gasket needs replacement.\u003c\/p\u003e\n\n\u003ch3\u003eWill these jars work for hot-fill applications like jam or hot sauce?\u003c\/h3\u003e\n\u003cp\u003eBorosilicate glass handles heat, but the plastic lids don't. don't pour hot liquid directly into the jars and immediately cap them. Let contents cool to room temperature, then seal.\u003c\/p\u003e\n\n\u003ch3\u003eCan I buy replacement lids separately?\u003c\/h3\u003e\u003cp\u003eYes, CR lids for this size are available as individual items or smaller packs if you need. Replace gaskets or expand your container stock.\u003c\/p\u003e\n\n\u003ch3\u003eAre there different lid colors available?\u003c\/h3\u003e\n\u003cp\u003eThis pack includes black lids. Kraft \u0026amp; Kitchen also stocks clear and amber glass jars in various sizes with different lid colors - check the glass jars collection for other options.\u003c\/p\u003e\n\n\u003ch2\u003eCare and Storage\u003c\/h2\u003e\n\u003cp\u003eWash the glass jars with warm soapy water before first use. Dry thoroughly. Store jars upright in a cool, dark place to preserve seal integrity. Hand-wash lids with mild soap and water, and air-dry completely. If the gasket hardens or cracks, replacement lids are inexpensive and available in bulk.\u003c\/p\u003e\n\n\u003ch2\u003eShipping and Returns\u003c\/h2\u003e\n\u003cp\u003eOrders ship within 1-2 business days from our Wisconsin warehouse.
