30 Days of Emergency Water Storage With Water Preserver 

• Emergency Water Solution - It's recommended that you have 1/2 gallon of water per person per day for any emergency. This will provide you with 30 gallons (6 containers that are 5 gallons each)- about 30 days of drinking water storage!
• High-Quality Containers - This Stackable Water Container Kit is made from 100 percent non-toxic food-grade plastic. That means there is no leaching and the plastic is more durable than others.
• Save on Space - These Stackable Water Containers allow you to save on space. Instead of laying your water containers all over the floor, you can stack them to decrease your storage space!
