We discovered that we received a faulty batch of lids with one shipment of Foldable Flasks. These lids did not have enough threads on them causing some lids to loosen and leak.

We have identified the problem and we have replaced the lids on all of our Foldable Flasks. We have tested the new lids and ensured that they are indeed secure. If you ordered your flask before October 5th, 2011 and noticed that your lid is loose, please let us know that you'd like a replacement lid and we will send one to you ASAP.
