WaterBricks are a great way to store water, food and more. With its puzzle-like locking design, they can be easily stacked up to four feet high without toppling over. They take up a mere fraction of space needed than most water storage units and have a long shelf life. Water bricks last 15 years or more thanks to a special UV additive that protects against cracks, leaks and any other damaging factors over time. The plastic that these bricks are made from is BPA free as well. Use these bricks to store water, food or anything you want to keep dry or stored efficiently while eliminating most food odors. Honeyville water bricks are an ideal product for long term food storage and emergency preparedness.
Shelf Life: The water bricks can last indefinitely when used properly. Keep in mind that you should rotate your water storage every 6 months.
