Listings show two close capacity options: 8.0 ounces and 8.5 ounces.
Many listings advertise airtight, leakproof, or spill-free performance. That sealing is typically achieved with a secure swing-top closure plus a thick rubber gasket (or similar seal) and a metal clamp to hold it closed.
The listings show two main material types: glass bottles (glass bodies) and clear plastic bottles made from PET or similar polyethylene plastics.
Common pack counts in listings include single bottles and multi-packs such as 6, 12, 18, 50, and 100.
Listings include clear/transparent plastic (PET) and glass bottles; some glass options are amber, which helps protect contents from UV light.
Some glass bottle packs include accessories; examples listed are a cleaning brush or bottle brush, a collapsible funnel, a gold glass marker, paper tags, and shrink wrap. Availability varies by pack.
