A couple of folks have complained about this....we have new cord locks coming early next week and we can send you one. The good news is that if you close it and can install the bottom flap with the buckles, you can actually operate the Bag just fine (everything will hold) and replace the cord lock in a few months when you do your first harvest. The compaction of the vermicompost should keep almost all of the material inside the bag so you shouldn't need to worry about all of the contents dropping out at once.
If you have any concerns just let us know.
