First of all I was struck by the size of the two ordered buckets. I have not measured it, but there are certainly more than 30 liters. I just needed containers, with lids for a garden house, which can also be stacked, there to store a variety of things. So far I had always this household bucket with clamping lids. But they are usually rounded in the lid, so that they and therefore actually can not be stacked space wasters.
These buckets I am now completely satisfied. The lid close on securely and they can also contribute to the handles.
