Query: Not airtight

I gave these four stars initially because they were cheap, did the job, and seemed to hold up pretty well despite being thin. However, these are not airtight as the description states which pretty much renders them useless. I used these to store flour, rice, cereals, and pet treats and all of the cannisters ended up with bugs in them. A lot of stuff to throw away. You're better off saving money in the longrun by spending more money upfront on better containers.
