Ddrops® products feature a Euro Ddropper® based dispensing technology. This allows one single drop of Ddrops® to be accurately dispensed, which can then be licked from a clean surface. Do not use a syringe, bulb-style dropper or other method of measurement. The exact amount is designed to come out of the Euro Ddropper® in each and every drop. Ddrops® products can be easily taken with you wherever you go, as they do not require refrigeration.
