THE TINCTURE BOTTLE

Borosilicate doesn't react with what's inside it. Standard soda-lime glass leaches trace alkalinity into acidic tinctures and oils over time — small enough to ignore once, cumulative if the bottle is in daily use. 30ml is the correct volume for a dropper format: enough for a month of daily use at standard doses, small enough that nothing sits in the bottle long enough to degrade. The amber blocks the UV wavelengths that break down light-sensitive compounds. These are not design decisions. They are the correct specifications.

Fill. Dose. Store away from direct light. Borosilicate glass. Dishwasher safe. Reusable indefinitely.
