Hi there Edelgado, Thank you for selecting Next Day Flyers for your printing requirements. We've numerous types of cardstocks for flyers. Seemingly, we would not have a water resistant content though we have h2o-resistant cardstock. Have a large amount to convey, but not much time for you to say it? https://travisdnsuv.nytechwiki.com/10217464/the_5_second_trick_for_flyer_printing
