Field note 03
Leak-conscious toiletry bottles with published capacities — TSA-era 100 ml logic, not influencer decant rituals.
Method on this page. Shortlist by stated capacity, closure type, and whether the maker still lists the SKU.
Airline security still thinks in 100 milliliters. The useful bottles publish that number (or 3 oz), name the closure, and admit they are not magic.
This hub covers Matador FlatPak bottles, Humangear GoToob+, and Cadence capsules — all of which have manufacturer pages with capacities. We do not invent leak-test scores. If you need a lab drip test, run one or read a publication that did.
Gasketed capsules for creams and solids. Cadence publishes volumes on keepcadence.com.
Locking silicone travel tubes. Humangear publishes 50 ml, 75 ml, and 100 ml sizes on gotoob pages.
Flat waterproof-ish soap case. Matador publishes dimensions on the FlatPak soap page — for bars, not liquids.
Flat-pack 90 ml / 3 oz class silicone bottle Matador sells for leak-conscious packing.
