Perfect for sealing my jars of body butter and facial care products
They work like they should! They do kind of stick together, so just carefully peel them apart, line up with the top of the jar, and then close the lid. Let them sit for a few minutes before trying to open them so they seal properly. I thought they weren't going to work for me at first, but then I let it sit and opened the jar again and they were perfect. I've already purchased another box!

Great seal
This is a great product. It seals the jars and make your products look very professional

Work great!
I read some reviews saying they’re not sanitary because of them just being thrown in the box, and that they didn’t stick because they had the printed label on both sides. Well here’s the solution… once you peel back one of the sides with the print on it, the label is now sanitary because that part wasn’t exposed to the elements, and will now adhere to the jar and remain sealed, after the 24hr wait period that’s indicated on the Amazon page with details and description. However, there were no instructions for the part about peeling the label back to reveal the plain white side, just trial and error taught me this, and it worked perfectly then, so I hope that helps.

Foam lid
These were a bit larger than my jars but fit nicely. They took a while to seal and some came off when removing the top. Overall nice

Product seals for protection
The 1st order i received was perfect. I ordered the same product and someone decided to vacuum seal the labels. The labels are stuck together. Unfortunately, i didn't use them as soon as I ordered them now I can't return them.

They work well
Fit our product nicely and did the job perfectly of sealing it! Although we wish there was an adhesive to simulate the peel off of market jars but that’s okay

Exactly as expected
Product works exactly as intended for mason jars. Delivers loose but the food side is protected as they are two together.

Did not work
It does not stick-wastage of my money. I should have read the reviews before purchase

They don’t all work
There’s no way to check to see if these actually sealed, other than unscrewing it and trying it yourself. If you’re doing a volume of lids it would be an extreme nuisance. I would definitely wrap an external seal around the outside of the lid again next time.
