SXUDA Mason Jar BPA-Free 4oz Mini Canning Jars with Regular Lids and Bands Jelly Jars for Jam, Honey, Wedding Favors, Shower Favors, Baby Foods, DIY Magnetic Spice Jars, 40 PACK

Pros: Much less expensive than jars I have bought in the past. Unfortunately that’s where it ends...Cons: The diameter of the opening is around 1/16” narrower than a standard Ball mason jar opening. This means Ball lids and bands that you can buy anywhere do NOT fit this jar, which is a bummer because I can’t find replacement lids on Amazon for this brand. So if you’re using these for canning, hopefully they are for one time gifts because you can’t can with them again if you can’t replace the lids. Also, I had seal failure on a few, which I never have with the more traditional brands. Last, the band is a little tight on the lid, so if you try to remove it for storage after processing you run the risk of pulling off the lid and ruining the seal.I can see where these would work well for wedding favors, candles and such, but not the best choice for fresh preserving.

Bought these jars for canning jelly. These are not suitable for water baths. Over 25% of the lids failed to seal, and 7 jars out of this box either had dented, misthreaded bands or chipped glass edges. Could not even use those for storage. Poor quality control on this product! These were a waste of time, money, materials and gasoline to have them delivered. Threw shabby bands and glass jars directly into the recycling bin. Very annoying. I wish my local hardware store hadn't closed so I could buy this product locally. Amazon shouldn't sell this product.

Since the lids do not fit well on the jars they are NOT good for canning. From my attempts 50% do not seal correctly which is disappointing for the effort in canning. I have used them for other things like crafts and leftovers with success which is why I'm not giving it a terrible rating but I definitely cannot recommend these for canning.

We ordered these jars for home canning purposes. We have found several of the jars cracked, or chipped. In all of my years of canning, I have never seen so many defects in a case of jars (I always use Ball Brand mason jars, tried these because if price). We have even found jars that were not damaged, but still had small shards of glass loose in the bottom of the jar. Keep in mind that these jars come with the lids on them. I’m not sure where all of the loose glass came from. I will NOT buy jars of this brand again. We have had 2 explode in the canner. I’m guessing they had a crack that we couldn’t see or the glass is just inconsistent in thickness? I’m thinking China needs to go back to the drawing board on this one.

I was a little skeptical due to some of the reviews.I'm happy I went ahead and ordered them anyway.I make Mason Jar cheesecake for my business.The jars were a perfect size.The quality was great.The lids fit perfectly and It came with individually wrapped tiny plastic spoons,labels and a tiny marker.Delivery arrived as scheduled.I'm extremely satisfied.***I ordered these once again.This time it was packaged as if done in a hurry.The mason jars are suppose to include a pack of labels enough for each mason jar and a small marker.There was not a package of labels this time instead I recieved One sheet of labels ripped on the side and the marker was loose.I ordered these Mason jars for a 3rd time.The package of labels weren't included this time.I am disappointed.Aside from that I will stand by my word as far as the great quality of the jars.*** I'm wondering why these no longer come with labels for each jar? The first box I recieved had them.I placed 3 orders since than that didn't include the pack of labels.This last delivery came with broken mason jars. It can happen while in the delivery process so I get it.Can y'all please make sure each box contains the pack of labels? I want to order again but am reluctant this time.

These jars are nice looking and easy to clean, but they are of inconsistent quality. I purchased them as party favors to put pickles into. I was disappointed to see that some of the jars, at least a third, don't close tightly and leak. Do not buy these jars if you plan to put liquids in them.

I needed something for storage of non-perishables, and Ball jars are expensive, so these are a great alternative if you're not actually canning or storing liquids/jellies. I can't attest to the seal. I put dried herbs in a few, but those don't matter much if they "breathe" a little, in fact I left some slightly open just in case they weren't done drying. I wish these were a little bit cheaper, seeing as how they're not Ball jars, not the same dimensions as Ball jars, and not approved for canning. But they serve my purpose, just be aware they're probably not a good idea for actual perishables.

The thickness of jars seem fine. Many of the lids and bands had defects. I didn't closely inspect the lids and bands when I opened the box - they looked fine from a quick glance. We were in the midst of canning when screwing the lids and bands onto the jar, I realized they varied in size enough to make some unusable. Approximately 40% of the bands had a dent - easily discernable when drying with a towel after sterilization. The lids also didn't pop down as reliably as brand name lids during the canning process. Given the shortage of canning supplies during COVID, they are a cheaper alternative, but be advised the seal may not be as reliable.
