New! Opal Applicator Tips are now available in replacement packs. Each replacement pack contains four tips. For best results, we recommend replacing your Opal Applicator Tip every 90 days. Removing and replacing the tip using your finger, fingernail or thumb, gently grasp below the rim of the hard plastic tip base and pop the tip off, being careful not to pull on the soft silicone. To replace the tip, press the tip firmly onto the black tip base. Listen for the snap for proper attachment.
