5% off 5+ units. 10% off 10+. 15% off 25+. No code needed at checkout.
Capacity: 6 milliliters (0.20 fluid ounces)
Material: Type I borosilicate glass
Closure: White silicone lid (included)
Design: Straight-wall cylinder with identical diameter from top to bottom, no shoulder taper
Best for: Dry goods, small beads, jewelry components, laboratory samples
Key advantage: No-neck design allows full scooping access and eliminates product waste in curved corners.
The 6ml no-neck jar eliminates the design flaw in traditional jars: wasted space trapped in the shoulder. A straight wall from rim to base means full access to every last bit of contents with a scoop or spoon. Borosilicate glass provides durability and chemical inertness, while the silicone lid seals tight without threads.
What's Included
- One 6ml borosilicate glass jar with straight-wall design
- One white silicone lid (included, replacements available)
Key Features
- No-neck design: The opening diameter matches the body diameter, providing unobstructed access to contents. No curves, no dead corners, no wasted product.
- Durable borosilicate glass: Type I borosilicate resists thermal shock, chemical exposure, and light impact. Safe for laboratory, pharmaceutical, and food use.
- Secure silicone lid: A smooth silicone cap seals the jar without threads, making it quick to open and close. The lid is replaceable if it ever hardens with age.
- Compact and stackable: The small 6ml size and flat base make these jars ideal for stacking in tight spaces, drawers, or custom-built storage systems.
- Optically clear: Borosilicate glass provides excellent clarity so you can identify contents at a glance and monitor fill levels.
- Affordable precision: At this price point, you can afford multiple jars for organized sorting without breaking your budget.
Applications and Use Cases
- Small-batch storage: Balms, salves, pastes, and other small-volume goods stay fresh, visible, and accessible. The no-neck design is especially popular for scoopable contents.
- Bead and craft component organization: Seed beads, findings, small charms, or jewelry components sort neatly into individual 6ml jars, stackable and easy to count.
- Dry goods and spice sampling: Test small quantities of flour, sugar, specialty salts, or ground spices in labeled 6ml jars.
- Laboratory and pharmaceutical use: Chemists and researchers use 6ml jars for precise small-volume sample storage and testing.
- Cosmetic and personal care samples: Eye shadows, loose powders, or specialty creams stay organized in individual 6ml containers.
- Herbal and botanical preservation: Dried flowers, plant specimens, or small herbal portions benefit from glass storage and the straight-wall accessibility.
How to Use (Step-by-Step)
- Unpack the jar and silicone lid. Wash both parts with warm soapy water and dry thoroughly.
- Fill the jar with your chosen contents. The straight-wall design allows you to fill all the way to the rim without wasted space.
- For scoopable items like thick balms, press a flat spoon or small spatula to the inside of the jar to ensure all product sits at the bottom and sides, ready for easy extraction.
- Place the silicone lid on top and press firmly to seal. A slight twist is optional but not necessary for an airtight seal.
- Label the jar with contents and date if managing multiple stored items.
- Store in a cool, dark cabinet away from direct sunlight and heat.
- To retrieve contents, remove the lid and scoop or spoon out what works. The straight sides eliminate product loss in corners.

Compared to Alternatives
No-neck jar vs. traditional shoulder jar: Traditional jars have a taper or shoulder between the opening and the body, creating an area where product gets trapped and is difficult to extract. No-neck jars eliminate that waste. For scoopable items, this design difference saves product cost and reduces customer frustration.
Silicone lid vs. threaded plastic cap: Silicone lids are quicker to remove and replace, don't wear out with repeated threading, and feel more premium in hand. Threaded caps are more formal for formal laboratory use, but silicone is ideal for daily use and consumer applications.
Frequently Asked Questions
Why is the no-neck design important?
Jars with a tapered shoulder trap product in the curved bottom of the shoulder where a scoop can't reach. The no-neck design eliminates this waste, allowing full access to every bit of contents stored inside.
Is the silicone lid food-safe?
Yes, the silicone lid is food-grade and safe for direct contact with food and consumables. It meets FDA standards for food storage.
Can I replace the silicone lid?
Yes, silicone lids can harden slightly with age and UV exposure. Replacement lids are available separately and fit the same jar base.
What is borosilicate glass?
Borosilicate glass (Type I per ASTM C225) is a specialty glass designed to withstand thermal shock. Chemical exposure, and repeated heating without cracking. it's widely used in laboratories and food production.
Can I use this jar for hot contents?
Yes, the borosilicate glass itself is stable up to 500°F. For hot liquids, allow the jar to cool slightly before capping with the silicone lid (which has a lower heat tolerance of 300°F).
How many 6ml jars fit in one storage drawer?
With a footprint of roughly 1 square inch per jar. A standard desk drawer can hold 50 to 100 jars depending on depth and your stacking method. Many users build custom bamboo or wood organizers to maximize space.
Care and Storage
Wash the jar and silicone lid with warm soapy water and dry thoroughly. Borosilicate glass is dishwasher safe. The silicone lid can be wiped clean or run through the dishwasher on the top rack. Store jars in a cool, dark cabinet away from direct sunlight, which can degrade the clarity over very long periods. Avoid thermal shock (rapid temperature changes) to maximize glass longevity.
