Unlike individual lash adhesives, strip lash adhesives contain natural rubber latex. Rubber latex keeps the adhesive pliable so they do not harden up completely and will remain somewhat flexible. This is the reason why you can simply peel them off when you are done with your falsies. The strip will come off easily. Individual lash adhesive is different and will require special remover solution to remove the lash clusters or extensions. You should never attempt to pull off the individual lashes directly.
