MasontopsTough Tops Tough Bands 4PK (Small Mouth) White TB4RWHT

These lids create a very tight seal that did not leak. Arguably their best and worst feature. The seal is so tight that my kids can't open them, my wife and I can get them open but it is a struggle. This makes them great for storage not so great for daily use.They seem well built and durable. We will continue to use them, but had to find a different solution for our daily use jar.

Good quality, come in a variety of colours and sizes. I'm on my fourth purchase. Highly durable and airtight. Don't waste your money on cheaper alternatives. Pay cheap, pay twice. I only wish they made them for 4oz 47mm lids. Also good if you want to avoid contact with metal lids which are highly poisonous to the body. Good quality BPA plastic is much easier to detox from the body than heavy metals such as aluminium.

These also fit the wide mouth 'Ball' jars, which I guess is the UK brand equivalent to Mason jars.They could be a little cheaper considering they are just 4 bits of plastic and silicon.But I've already wasted a bunch of money on other lids which were utterly useless, so it's hard to grumble about the price too much

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).

I use the Mason Baby straw lids with my toddler, but if she throws/drops them on the ground, the metal bands get dented and then leaks happen. I decided to invest in some plastic bands… so I have tried a few styles. Even other bands claiming to be durable have ended up cracked pretty quickly. These have really been holding up! My 6yo did drop a jar out of the fridge recently and the band cracked, but it saved the jar so that’s a win. Overall with the number of drops we’ve had, I’ll take a loss of one. These are the best on the market that we’ve found! Also from a good company.
