1. Upon opening the refill product, please remove the cap from the unit. With a pair of scissors, cut close to the tip a slight angle to allow the gel to flow.
2. In order to replenish the CleanBlock, with the tip of the bottle that you made a cut, gently slide insert inside of the rubber where you would normally insert a writing instrument
