All natural sea sponges contain no chemicals or synthetic fibers, making them the natural choice for women looking for discrete protection. Comfortable and easy to use, our sea sponges conform to the natural curves of your body. Includes washing and usage instructions, 2 sea sponge tampons, 1 embroidered muslin bag (flower embroidery will vary). To use: Wash hands thoroughly before handling your sponge. Wet your sponge and squeeze excess water out. Squash the sponge between your fingers and insert it into your vagina, pushing it in until it feels comfortable and securely in place. Every 3-4 hours, remove your sponge by gently pinching a large portion and gently pulling out (bearing down lightly might help push the tampon down for easier retrieval). Rinse thoroughly, squeeze out excess water and reinsert. To clean: Do not boil! This will toughen and deteriorate them! Natural cleansing methods and ingredients do a better job and do not upset your pH balance like detergents. Our recommendations are to soak in any of these solutions for 15 minutes or more:1 tsp. colloidal silver mixed in 1 cup of warm water.1 Tbsp. baking soda mixed in 1 cup of warm water.2 Tbsp. hydrogen peroxide mixed in 1 cup of warm water.2 drops of tea tree oil mixed in 1 cup of warm water. 1 tsp. of sea salt mixed in 1 cup of warm water.Another wonderful sanitizer and bleacher is sunlight. Make sure you clean and dry your sponges at the end of your cycle and store them in your bag when not in use.
