Loll took their 100% recycled containers and decided that the best interior liner would be something that already exists and is readily available to everyone. The Loll Mondo Collection was designed to work with 5 gallon pickle buckets. 5 gallon buckets are an easy way to move plants around when the weather turns cold or you feel like rearranging. Containers can be used without the liner buckets too, giving you even more options. Buckets not provided.
