This bag will be awesome for taking on cruises! The magnets are extremely strong and easily secure the bag, even when it's full. The size is perfect for a week's worth of toiletries--it measures approximately 7.25x10.25x4 inches. Despite the heavy Cordura fabric and the magnets, the bag reasonably light, weighing approximately 10 ounces. The bag is lined with a thick layer of what appears to be TPU, so the interior is not puncture resistant like the outside. I would recommend putting clippers, tweezers, scissors, or other poky objects inside a pouch first. The zippers are also not waterproof, so although this bag should contain most spills adequately, I wouldn't consider it truly waterproof, just water resistant. The zippers are high quality and operate smoothly. The main zipper has two pulls, so it can be opened in either direction. I absolutely love the handle on the side--it's very sturdy and comfortable in your hand. The entire bag is impeccably sewn, as I've come to expect from Living in a Bubble products. Two thumbs up!

Used to have our sunscreen and fly spray rolling around the dash, getting cooked in the stinging sun. Now it’s all tucked in this bag stuck to the door wall.
