They are great for storage. I also use them in 5 gallon buckets as a "burp chamber" if I trimmed and jarred my nugs before it was optimal. I'll open my jar, stick it in the bucket,seal the gamma seal lid, give it 5-10 minutes, then open up the bucket and put the lids back on my jars. I do this so I can maintain my 60°-65° and 60% humidity environment while having to cure.
