MasontopsTough Band - Wide Mouth Mason Jar Screw Bands - Quality Plastic Replacement Ring Seals & Jar Covers

These are sturdy and strong. They work well with my regular mouth mason jars and our Mason Bottle nipples. A+++ Highly recommend!

I love these with the burping pieces and really like that they won’t rust like the metal ones!!! Love that they should last along time and won’t rust!!!

Nowhere on the packaging does the manufacturer specifically claim that these plastic rings are a substitute for metal bands when processing home-canned foods. As an experienced home-canning person, I recommend you stick with metal bands for putting by your produce, as there is no evidence that these plastic rings would not fail during water-bath or pressure-canning.That said, I bought these rings to use with the "Ball" Brand Sip & Straw Lids (for small-mouth jars). The plastic rings fit fine over the straw-holder insert. Because the straw-holder is ventilated and there is a gap around the straw when it's in its hole, whether or not the ring is leak-proof is a moot point. They're a little on the pricey side, but because the straw lids don't come with rings, they were worth it, to me.They sell solid plastic lids for use when storing an opened jar of home-canned food, and I prefer to use those instead of a ring and the metal canning lid. But if giving a jar of home-canned food as a gift, and you don't have a solid lid to include, the plastic ring makes a better presentation than a rust-prone tin ring.These plastic rings look sturdy, and would probably give years of satisfactory use when sprouting seeds for salads.As a non-food use, a crafter could use these rings to secure a handmade round pincushion to the top of a button jar.Incidentally, I use half-liter jars made in Italy, and like the American standard small-mouth canning rings and lids, these plastic rings also fit.

Work great. Better than the steel rings; easier to get on/off and don't rust.

They work just not very sturdy.

I like the way they are shaped. They work beautifully and I use them for when I have leftovers. So much easier to store leftovers in a mason jar with these hand friendly lids. Dishwasher safe. Perfect for me to use. Highly recommend.

LOVE these wonderful Mason Jar rings! Zero leakage and 100% foolproof. So much more economical than fancy travel mugs, and perfect for air travel. Now I take my empty jar (with inexpensive canning lid and new leakproof ring), fill it with water at the airport and just add a packet of drink mix. Such a simple solution!

Exactly as described and Exactly what I needed. Price seems high but they are good quality it seems.

No rusty rings! I use wide mouth mason jars for storing food in both my fridge and pantry. These can be washed over and over and no issues! Win win.

Was looking for something so I could use my mason jars as spice jars and this works perfect to hold the spice top on! I love it! 🙂

Great sturdy lid sides that fit regular mason jars. I use with 'pickle pipes' for salt pickling or a round piece of plastic embroidery mesh for sprouting beans/seeds (as metal mesh lids always seem to rust).

Have used these bands in the past and because they are plastic the don’t rust like the metal bands when fermenting. Unfortunately, these were shipped with another item in an envelope which got ripped at some point during shipping and the box containing the bands fell out. At least the other item was large enough that it didn’t get lost as well. Amazon refunded me for the missing item and I will be re-ordering the bands in the near future. Hopefully this time they use a box instead of an envelope. To be clear, this was not the fault of the seller as it was Amazon who packaged and shipped the items. This is also the first time something like this has happened and they were quick to issue a refund so it is all good.
