5ml DBLB EYELASH  GLUE IS DESIGNED FOR ONLY EYELASH EXTENSIONS AND PROFESSIONAL USE.How to use?1. Before applying this product, be sure to clean and dry off eyelashes and make sure there is no dirt, oil or makeup around the eyes. Always make sure the artificial hairs are clean and free from any contaminants, especially mold spores.2. Remove the glue container from the aluminium foil lined plastic bag. 3. Shake the container for 30-60 seconds to ensure the contents are completely mixed together. If you do not fully mix the contents before each use, you will run the risk of having inconsistent drying and bonding times as well as inconsistency in your work. 4. Hold the bottle at a 45-degree angle and twist the cap to open. 5. Make sure not to put the lid down on top of any contaminants, or onto an uneven surface so it can not roll onto the floor. 6. Gently squeeze the belly of the container with your finger and thumb, and keep the tip of the opening facing downward, squeeze out 2-3 drops of glue onto your crystal, jade pallet or glue sheet. 7. You should cover approximately 3 mm of the base of the eyelash extension with glue, being careful not to adhere to the tweezers or contaminate the hair or glue with dirt or oil from the skin. 8. Make sure not to attach the eyelash extension coated in glue any closer than 2mm from the eyelid. 9. When attaching the extension to the natural lash be sure to hold it for 2-3 seconds to ensure the bond-this will help you to avoid gluing the next eyelash to the last extension you just completed. 10. Once you have completed the final eyelash extension, the surface of the giue will take approximately 5 minutes to cure, while the center of the glue can remain pliable for up to 24 hours after the treatment. LASH TIP You can reuse the aluminum foil-lined bag your glue came packaged in. Store your glue in the bag to preserve it while not in use.
