bioDOGradable Bags have a shelf-life of 12-18 months and will not start to degrade till then, so there is no need to worry when buying large quantities of these compostable bags.
Remember: bioDOGradable Bags only start to degrade within 3-6 months after use when the micro-organisms start to eat away at the bags. This pack of 240 dog poop bags should last you a long time, that is unless you are the parent of many dogs!
