80ml 9% 11% 14% 17% 20% Silver Nitrate election ink with brush head

The most commonly selected silver nitrate concentrations for this election ink are 9%, 11%, 14%, 17%, and 20%, respectively. We have determined that a concentration of 25% is the strongest and optimal amount of SN in our non fading ink. We have our own ink factory and later introduced lower concentrations, maintaining an advantage in terms of price. This election ink imprint is retained for more than 72 hours and is widely used in African elections.
