I've been using these jars for my candle business for about a year now, and I have absolutely no complaints! They're beautiful, straight jars, and even though the lids don't 'fit' perfectly, they still look quite nice. If you didn't know any better, you'd just think they were supposed to be that way. I do also wish that there were threaded lids for these, or that Candlescience would get some straight sided jars that the threaded lids worked on, but I still love these. I get compliments on my candles all the time!
