ComSaf Wide Mouth Glass Mason Jars, 960 ml, 2 Pack with Two-Piece Lids

Some preserving jobs call for large volumes, others are easier to manage in smaller batches. The ComSaf wide-mouth glass jars hold 960 ml each and come as a two-pack. They suit home preserving, fermentation and everyday pantry storage. The broad opening also makes filling and cleaning easier than with a narrow-neck jar.

Practical tips

Use the jars for small batches of pickles, kimchi, chutney or other fermented vegetables, or for keeping dry ingredients such as lentils, nuts and pasta organised. The clear glass makes contents visible, while the two included labels can help distinguish what is stored or note a preparation date. For a practical fridge use, the jars can also hold overnight oats or prepared ingredients.

The glass is dishwasher compatible, but the metal lids need different care: hand-wash them and dry them straight away to help maintain their rust-resistant finish. The jar is described as freezer safe, leave headspace if freezing. Avoid sudden temperature changes greater than 40 °C, preheat the jar before hot filling, and do not use it in a microwave or oven. These details matter more than the general convenience of a reusable glass container.

Where it shines

The 960 ml capacity is aimed at manageable household quantities rather than very large preserving batches. That makes the pair useful when you want to keep a ferment in progress alongside a second jar of pantry staples, or prepare a small quantity without taking up space with a much larger container. The 7.6 cm opening helps when adding chunky ingredients, spooning contents out or reaching the bottom for cleaning.

Customer feedback often highlights the useful size, wide opening and lids that screw on securely and come apart for cleaning. Labels and appearance also receive positive mentions. There is a practical caveat: some buyers report rust on the lids, so prompt hand-washing and drying are worth taking seriously. The manufacturer describes the finish as rust-resistant, not maintenance-free.

Key features

Each clear, round jar is made from food-contact-safe soda-lime glass and measures 10L x 10W x 16.8H centimetres. The screw-top closure uses a two-piece lid design, and the stated wide-mouth size is 86mm, compatible with universal 86mm accessories. The jars are presented as airtight and suitable for water-bath canning, with the vacuum seal forming as the jar cools. No fermentation airlock is listed as included, so that would be a separate consideration if you need one.

It makes sense if you want two versatile jars for modest preserving batches as well as ordinary cupboard or fridge storage. It might not be a great match if you need a microwave- or oven-safe container, or prefer lids that can be left damp after washing. For canning and fermentation, follow a suitable process and the stated care guidance within these limits.

Before you decide

Can the jars go in the dishwasher? The glass jars are dishwasher compatible, the metal lids should be hand-washed and dried immediately.

Are they suitable for freezing? They are described as freezer safe. Leave headspace and avoid abrupt temperature changes.

Will wide-mouth accessories fit? The opening is stated as Standard Wide Mouth (86mm), with compatibility for universal 86mm accessories.

Should you buy it?

Choose this ComSaf set if two clear, near-one-litre jars would cover a mix of small-batch preserving and everyday storage. The wide opening, labels and two-piece lids give it uses beyond a single ferment or preserve. If your priority is oven or microwave use, or a lid requiring no particular drying care, the stated materials and care instructions point towards a different type of container.
