We appreciate you sharing your thoughts on the Honeycomb Waterproof Dry Bag, and regret to hear the bag wasn't to your expectations. Please note, the honeycomb waterproof dry bag uses the roll top closure for snapping onto belts or other bags. This detail is listed under the product description, however, we will be sure to share your feedback to our team for more details on how to use the bags for best results. We recommend rolling down the top edge 3-5 times then fasten the buckle for best results with securing the contents in the bags. Please ensure all air is pushed out before doing this step. We hope this is helpful.
