Longer-lasting freshness - with airtight metal lids

Metal lids compress against the glass rim to create an airtight, watertight closure that limits air and moisture ingress. Food-grade materials reduce contamination risk during short- to medium-term storage.

Airtight lids prevent leaks and slow spoilage, keeping jams, chutneys and sauces fresher for longer. Watertight performance also protects against spillages during transport.

Quick cleaning and reuse - with wide-mouth glass construction

A 7cm opening and smooth, clear glass interior reduce crevices where food can collect, and the jars are dishwasher-safe for straightforward cleaning.

Cleaning takes seconds and repeated use is simple, so jars work well for meal prep or regular preserving. No fiddly corners means fewer residues and less scrubbing.

Flexible for kitchen and crafts - thanks to clear, sturdy glass

Solid, transparent glass shows contents at a glance while silver metal lids withstand repeated sealing and opening. Reusable design supports multiple household uses.

Clear jars suit food storage, pickling, honey, and homemade gifts or candles, making them useful beyond the pantry. Durable construction supports crafters and small-batch sellers alike.
