Review (5/5): They are good for me.
I found these after switching from my last containers that cracked when reacting with the fragrances in my products. And I'm not sure why it happened but I found these and they were little more expensive then to my other packaging's that had screw on lids but so far I saw that these were pretty good and so far I haven't had much leakage I think only about 1 out of a customer box leaked, and I wrap it in shrink wrap as well so I'm not sure if it was just not put on right or it just so happens that that one decided to leak but in the future I think I would like these for sure when I go to farmers markets and give out samples. I like that they come with little stickers to. And I even use the little plastic spatulas from time to time.
My only one complaint is that I think about one out of every ten or more has these black spot in perfections in them and I'm not sure what they are. So I don't use them. Some are just little specks some are definitely noticeable and so that it's just my only complaint. Other than that I really like these for sure. I haven't had any problem with them other than those.
