Ardell Individuals DIY Starter Kit, Organic Knot-Free Naturals Lash Clusters with Adhesive Remover & Tweezers for DIY Lash Extensions, Black, 1 Pack

You could try the ardell individual lash kit. It’s a different style of lashes and glue, but the glue dries hard. I’d practice before vacation though, as these are more difficult to apply than modern clusters. You still may need to touch them up too. https://a.co/d/0hIHI16Q
