Kook Glass Apothecary Storage Jars (36 oz, Set of 2)

Glass-Lidded Apothecary Jars for the Kitchen or the Bath

These Kook apothecary jars are the classic rounded canister shape, and what sets them apart for a microplastic-free kitchen is the lid: it is a removable glass lid with an easy-grip knob, not a plastic snap-top.

With a glass jar and a glass lid, the only material your food touches is inert glass. The set is two 36-ounce jars in thick, chip-resistant clear glass, with a wide mouth that makes them easy to fill and scoop from, and a tight-fitting lid that keeps contents fresh.

Their rounded apothecary silhouette is genuinely versatile. In the kitchen they hold flour, sugar, pasta, cookies, candies, coffee, and tea while looking good on a counter, and in the bathroom the same jars tidy up cotton balls, swabs, and bath salts on a vanity. They are dishwasher and freezer safe, so cleanup is simple, and as glass they will not stain, warp, hold odors, or leach into whatever you store.

True Shift Score: 8.2 / 10

This is our own assessment, not a lab result or a certification.

It scores well for being a genuinely glass-on-glass jar, a glass body with a removable glass lid keeps your food on inert materials, in an attractive, chip-resistant, dual-purpose design that is dishwasher and freezer safe. It sits below the clamp-sealing jars on our scale for honest reasons rather than material ones: the glass lid seals by fit rather than a gasket so it is not vacuum-tight, the 36-ounce size is moderate rather than bulk, and glass is breakable. For everyday plastic-free dry storage with a clean look, it is a solid choice.

The Honest Tradeoffs

A few honest notes.

1. The glass lid sits and seals by fit rather than by a clamped gasket, so it keeps contents fresh for everyday dry storage but is not a vacuum-tight canning seal, for true airtight preserving, a gasketed or clamp jar is the better tool. 

2. At 36 ounces these are a moderate counter size rather than a bulk-storage jar, so for large quantities you would want something bigger. 

3. And like all glass they are sturdy but breakable, happiest on a shelf or counter rather than tossed in a bag. 

4. For their job, attractive plastic-free dry storage you can see into, they do it well.

How We Evaluate Food Storage

We look at four things, and none is a lab score:

1. Whether the food-contact surface is inert and won't leach

2. Stain, or hold odors, what the lid is actually made of, since that is where plastic hides in most "glass" storage

3. How well it seals and holds up across the fridge, freezer, microwave, and dishwasher, 

4. And how durable it is over years of use. 

The real shift in food storage is getting your food off plastic and onto glass.
