Review on YUMQUA Clear Waterproof Bags: Versatile Water Tight Cases & Pouches for Camera, Mobile Phone, Maps, and More - Ideal for Kayaking, Military, Boating, and Document Organization by Kenny Hrdlicka

When I first got them, I tested them by putting toilet paper in bags, sealing them, and then showering with them on the bottom of the tub. I figured if any paper product couldn't withstand water, it would be thin and thin toilet paper. Get out of the shower, wiped the outside of the bags and the toilet paper in the bags was 100% dry. Taking this product to the beach I was very happy with how it protected our phones from the sand and water. and other products.
