  • Sealing Performance: Airtight and watertight seals preserve freshness, supported by durable silver metal lids
  • Best for: Meal prep, homemade jam, overnight oats, pickling and preserving

Keep food fresher for longer - thanks to airtight, watertight seals

Durable silver metal lids close tightly against the jar mouth to form an airtight, watertight barrier. Food-grade glass resists odour absorption while blocking air and moisture contact with contents.

Jams, pickles and overnight oats maintain texture and flavour for longer, reducing waste and keeping stored items ready to use.

Quick, low-effort cleaning and reuse - with dishwasher-safe, BPA-free glass

Solid clear glass is specified as dishwasher safe and the set is 100% BPA-free, allowing safe repeated use for food storage. Lids are described as durable metal suitable for regular cleaning.

Load jars and lids straight into the dishwasher after use, making rotation between batches simple and hygienic for frequent preserving or meal prep.

Versatile for kitchen and crafts - with generous 1 litre capacity and clear glass

Each jar holds 1000ml and the clear glass body keeps contents visible for easy identification. The robust construction supports multiple uses, from foodstuffs to lotions and candle making.

Large volume suits batch cooking, small-batch preserving and hobby projects, reducing the need to buy separate containers for different tasks.
