- Are these jars truly airtight?
- Yes. The clip-top lid compresses a rubber gasket against the glass rim, which seals dry goods and preserves. Check the gasket sits evenly and replace it when it hardens.
- Can I put them in the dishwasher or microwave?
- The glass is dishwasher safe, though hand-washing the gaskets and clips extends their life. They are not microwave safe.
- What fits in a 500 ml jar?
- Roughly a standard bag of coffee, a small batch of jam or chutney, or about 400 g of flour. The square body holds more than a round jar of similar height.
- How do these compare with Kilner's round clip-top jars?
- Same clip and seal system, but the square body packs tighter on shelves. The trade-off is a narrower mouth than the round jars.
- Are replacement seals available?
- Yes. Kilner sells replacement rubber seals for its clip-top jars, so the jars can be resealed when gaskets wear out.
- Is this a set of six?
- Yes, six 500 ml jars with clip-top lids and seals are included.
