I can’t get a drop out of the JBL NanoCrusta bottle. The product has become encrusted in the neck of the bottle.
JBL NanoCrusta is a product which contains finely ground natural minerals. We recommend you shake the bottle vigorously before every use, to loosen the sediments. Ensure that the bottle is in a vertical position for the application. If the dosing device remains blocked, pierce the sediments inside the channel with a fine needle.
