So it’s not exactly drugstore, but it’s my HG! Peripera Ink Mascara in Full Volume… it’s under 10$ on Amazon and it really stands up to Florida summers. I’ve gone to the beach wearing it and not a smidge in sight! I will say it’s not “difficult” to remove but it isn’t easy either… it needs an oil based remover or cleansing balm (I use Grapeseed Oil or Neutrogena cleansing balm)
