The 9ml round-bottom jar combines maximum capacity with complete product recovery. At this size, a flat bottom would leave recoverable product in corners, which translates to wasted revenue at volume. The curved bottom lets users squeeze out every bit through natural flow and simple scraping. Borosilicate glass resists degradation, the child-resistant black lid meets ASTM D3475 standards, and the 9ml capacity serves as the retail standard.

How to Use (Step-by-Step)
- Wash the jar and lid with warm soapy water and dry completely before first use to remove manufacturing residue.
- Fill the jar leaving approximately 0.2 inches of headspace for proper lid seating and compression.
- Place the black lid directly on the jar opening, ensuring the gasket sits flat against the glass rim.
- Twist the lid clockwise until it stops naturally. The gasket will compress slightly, creating an airtight seal.
- Verify the seal is secure by gently pulling upward on the lid. Proper sealing creates noticeable resistance.
- Store upright in a cool, dark location away from direct sunlight to maximize product freshness.
- When opening, twist counter-clockwise. The lid will pop slightly as the seal releases.

Care and Storage
It's simple: we'd suggest a quick rinse with warm water and mild soap. You're set for years if you don't let residue build up.
Wash with warm soapy water and dry completely before first use. Store upright in a cool, dark location away from direct sunlight. The airtight seal maintains integrity indefinitely when stored properly. For reuse, a hot water soak followed by an alcohol wipe fully restores the jar. The curved bottom design makes it easy to access every bit of remaining product, no corners to leave residue behind.
