Our pro-made fans are lightweight and have minimum glue at the base. Therefore, when you dip them into the glue, it absorbs a tiny amount of glue. Consequently, it would be best to dip at least 1s so the base will take enough glue. (Tips: when you take it out of the glue dot, it should be bed coated with a soft blob of glue around). You should apply from the underneath or one side of the natural lashes. After positioning rightly, hold them for 0.5-1s for better attachment. The recommended glue: 1-2s with a medium thick viscosity.
