Review: 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!
*by R***O on September 21, 2022*

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.
