So far, very good
I bought these because I had a HUGE bag of wonderful tasting heirloom garlic cloves that I couldn't possibly get through.  So, I minced and froze them into very small ice cubes.  I keep these in the freezer - it's fast and convenient and the flavor is good, even frozen.<br /><br />When I removed the garlic from the ice cube tray, the tray reeked - I still haven't gotten the smell out of that.  Now, the garlic small has easily seeped out of the plastic baggie and is permeating all the other frozen food.  I didn't want garlic flavored ice cream!  I moved the garlic as far away from sensitive items as I could, but it was still a problem.<br /><br />I put the garlic in these bags a few weeks ago.  I pulled out a bag of it yesterday and smelled - I couldn't smell anything.  I was wondering if I might also use them to store nuts - if it keeps smells in, it might keep smells out, too.  Nuts often pick up off smells along with garlic or onion smells.<br /><br />My only criticism is that these are pretty small.  These are smaller than a small sandwich baggie, I'm pretty sure.  I had to use 3 or 4 of these just for the garlic.  I just looked up the size of a sandwich baggie -it's 6.5 by 5.5.  These are 5 x 6.  While that doesn't seem that much smaller, coupled with the fact that they don't have a pleated bottom and that the material is very sturdy/firm, these  just don't have the same amount of space I would have preferred.
