Kilner® Zestaw 6 szerokich gwintowanych obręczy

These fit my 0.5 litre jars perfectly, so I ordered two sets to have spares ready. The threading is smooth and they screw on tight without any wobble, which is exactly what I needed for my regular canning batches.

My old bands were getting rusty so I grabbed these to fit my 0.5 litre jars, and they thread on just as snugly as the originals did. The wide mouth design makes clamping down the lid a breeze, and they've held up perfectly through a few dishwasher cycles already.

Bought these as replacements for the 0.35 litre jars I use for jam, and the threading is identical to the originals—they screw on smoothly with no wobble. The metal feels sturdy enough for repeated boiling, which is what I needed.
