I had to google Fowlers jars. Specific to Australia, it appears. They look quite interesting but I'd be worried about the metal lids - are they coated on the inside? Also being screw top might be problematic for using for fermenting veg, sauerkraut and the like. Unless, of course, you're very diligent at burping them daily often for several weeks. I ferment veg directly in the jars, in fairly small quantities and the jars I use more or less burp themselves after the first really vigorous fermenting stage which is only a few days really.
The older Kilner jars with metal discs were similar. Not great for preserving anything acidic. Or fermenting in-situ.
In the US they have Mason jars or Ball jars which again pose the similar problems for fermenting and acidity, as above.
There are also all glass Weck jars which are lovely but the rubber washers are very flimsy and require replacing regularly and the metal clips which hold the lid on are very easy to lose - don't ask me how I know!
I use the newer, glass topped Kilner jars, as you can see in my avatar. I say newer but some of mine are forty-odd years old. I have all sizes and shapes and use them for just about everything from storing spices, in the small ones, through making mayonnaise etc and storing coffee beans and dried pulses in the middle size ones to, as I said earlier, fermenting veg in the 2 litre and above sizes. And my milk kefir has been housed in a 1.5l jar on my worktop for the last ten years or so.
The best bit for me is that the rings are sturdy and last for ages and are fairly cheap to replace, as are the wires. If we break any (which is thankfully rare - they're pretty sturdy) we just keep all the unbroken bits to replace worn out/broken bits on other jars. I have fifty or more of these things, some in long-term storage use others used daily or weekly.
Le Parfait do similar jars and are also very good although I haven't seen that brand for years. There are cheaper versions of these types of jars but be careful. From experience I've found the wire clasps flimsy, so they don't create a good seal, and the rubber rings similarly unsatifactory. I'm sure they're not all like that but sometimes it's easier to go with what you know, than keep being disappointed.
(I'm expecting a surprise parcel of jars, from Kilner, when they see this endorsement.
