The 2 oz Tincture Bottles that we offer come in a matte black finish. This allows the bottle to store light sensitive tinctures and medicine oils for prolonged periods of time. These dropper bottles allow for easy storage and measured distribution of precious medications when paired with our CR graduated 2 oz dropper (included). Featuring the classic ingenuity of the dropper design, these glass dropper bottles make accurately calculating dosages intuitive. These tincture bottles are ready to be wrapped with your branding or any warning symbols to follow state regulations.
