To help keep children out of your tinctures. I have obtained some nice child-proof dropper tops (glass of course), which are relatively easy for an adult to open. If you need one (or more) of these, just add it to your cart and it will come as an extra dropper top in addition to your order.
Child-proof caps for the small half-ounce tincture bottles come only in WHITE.
Child-proof caps for the larger one-ounce and two-ounce tincture and colloidal silver bottles come in bright RED. The same top fits both of those sizes of bottle.
NOTE: These dropper tops do not fit the essential oil bottles, which come with a drip restrictor inside the cap to make them harder to spill.
The photo here shows one of the red child-proof dropper tops on an aqua glass one-ounce bottle.
