Seven milliliters is about a quarter of a fluid ounce. Enough for a serum sample, a pinch of saffron, a single batch of pigment, or a trial jar for a retail line. The glass is thick-wall borosilicate with UV protection, clear enough that customers can see what they are buying. The black push-and-twist lid is the real thing: certified to ASTM D3475 and 16 CFR 1700.20, with an airtight, odor-proof gasket. Easy for an adult, mechanically frustrating for a toddler.
The round bottom is not cosmetic. A curved interior means a spatula or pick reaches everything, so nothing gets left behind when the jar is scraped clean. If you fill these in volume, that adds up.
First use: wash with warm soapy water, dry, fill with a hair of headspace, press the lid down flat and twist until it stops. A gentle upward tug confirms the seal. To open, push down and twist the other way.

Common questions
Are these actually certified child-resistant?
Yes. The push-and-twist lid meets ASTM D3475 and 16 CFR 1700.20. Push down and twist to open; either motion alone does nothing. Harder to defeat than the average pill bottle, though nothing is toddler-proof forever.
Can I use these for food?
Yes. The glass is food-grade. Spices, honey, coffee, tea, dry goods all work.
Are they dishwasher safe?
Both jar and lid are top-rack safe and the glass will not cloud. Hand-wash the lids now and then to keep the CR mechanism smooth.
Why the round bottom?
A curved interior has no corners for product to hide in. In the original spec that recovers 8-12% more product than a flat bottom, which matters when you are filling hundreds of jars.
