Good, but not great. The Food Kozy comes pre-folded, making it somewhat difficult to wrap anything that does not fit the standard square size. If something is oddly sized, sometimes the velcro strips will not meet, or there are large gaps in the wrapping. But for wrapping square-shaped sandwiches, it works very nicely. We also use them to keep cheese in the fridge, and they work very well for that.
