Mason Jars

Large glass mason jars built for real kitchens — from 64 oz half gallon jars up to 1 gallon, 1.5 gallon, and 2 gallon sizes, in classic round and space-saving square shapes. Every jar is thick, food-grade glass with a true airtight lid: choose metal, wooden, plastic, swing-top, or hinged closures depending on how you store. A 1 gallon jar swallows a full 5 lb bag of flour; the 2 gallon handles warehouse-club hauls of rice, beans, and pet food.

These wide mouth jars accept a full measuring cup with room to scoop and level, which is why they end up as flour jars, coffee bean canisters, sun tea brewers, and fermentation vessels all over the country.

Replacement wide mouth lids are always in stock, and everything ships in protective glass packaging from our family-run warehouse in New Jersey — free US shipping over $20.
