ComSaf Airtight Glass Jar 34oz Set of 3

No — these jars should be hand-washed only. The rubber gasket and clip mechanism aren't designed for dishwasher heat and pressure. This is actually pretty standard for glass jars with rubber seals. For tea storage, the jars don't get very dirty anyway — a quick rinse and dry between tea varieties is usually all you need. Just make sure they're completely dry before refilling with tea, since any residual moisture can affect your tea's freshness.

This is worth knowing before you buy: several reviewers dispute the capacity claims. The listing mentions 78oz for the set, but reviewers report the jars don't hold as much as expected. Specifically, a standard 5-pound bag of flour or sugar won't fit — it holds closer to 4 pounds. For tea storage, this is less of an issue since you're typically storing smaller quantities, but if you were planning to use these for bulk dry goods alongside your tea, you might need to buy more jars than you initially think.

They're a great fit for anyone who wants attractive, functional tea storage without spending a fortune. The set of three is especially useful if you keep multiple tea varieties — one for your daily black tea, one for green or herbal, and one for a specialty tea or matcha. Reviewers mention they look great on display, so they work well if you have open shelving or a visible pantry. They're also popular for RV and motorhome kitchens where space is limited. They're probably not the best choice if you need to store very large quantities of tea, if you want something shatter-proof for a busy kitchen, or if you need to run everything through the dishwasher.

The rubber gasket is what makes the seal airtight, and a couple of reviewers have reported the gasket breaking or wearing out over time. The bigger concern is that replacement gaskets aren't readily available from ComSaf, so if the seal goes, you may not be able to fix it easily. For daily tea storage — opening and closing the jar once or twice a day — the gasket should hold up for a good while. Just avoid pulling or stretching the gasket when you clean it, and don't expose it to very hot liquids, which can degrade rubber faster.

Absolutely not — this is a safety issue. Multiple reviewers warn that these jars are NOT safe for canning or hot liquids. There are reports of the glass cracking or even exploding when exposed to high heat. These are designed for dry storage at room temperature or refrigerator use. If you need to store brewed tea, always let it cool completely to room temperature first. For actual canning, stick with purpose-made canning jars like Ball or Kerr.

Brewed tea needs to be refrigerated and consumed within a few days. These ComSaf jars can hold brewed tea in the fridge — the airtight seal will keep it fresh and prevent it from absorbing fridge odors. However, there's an important safety note: do NOT pour hot or boiling tea directly into these jars. Multiple reviewers have reported that hot liquids can cause the glass to crack or even shatter. Always let your brewed tea cool to room temperature before transferring it to the jar. The 34oz size is about 4 cups, which is a reasonable amount for cold-brew or iced tea.

Unwrapped tea bags lose freshness fast because they're exposed to air and moisture. An airtight container like the ComSaf jar is exactly what you need — the rubber gasket seal locks out humidity and keeps the flavor from going stale. The 34oz size can hold a good stack of standard tea bags, and the clear glass lets you see when you're running low. One practical tip: the jar opening is wide enough for tea bags but not huge, so you'll be pulling bags out one at a time rather than reaching in with your whole hand. That's actually fine for tea bags — it keeps you from disturbing the rest of the stack.

For tea storage, you want an airtight container made of non-reactive material that blocks moisture. These ComSaf glass jars check the airtight box — reviewers consistently praise the rubber gasket and clip-lock mechanism for keeping contents fresh and moisture-free long-term. The one trade-off with clear glass is that it doesn't block light, which can degrade tea over time. If you're storing tea on a counter or shelf that gets direct sunlight, you'd want to keep these jars in a cabinet or pantry. For dark storage spots, though, they work beautifully — the clear glass actually becomes a perk because you can see exactly how much tea you have left.

Matcha is one of the most storage-sensitive teas — it needs airtight protection from air, moisture, and light. The ComSaf jars nail the airtight part with their rubber gasket seal, and reviewers confirm they work for coffee grounds and matcha powder. The main consideration is light exposure, since matcha degrades quickly in sunlight. Store the jar in a dark cabinet or pantry rather than on a bright countertop. The 34oz size is actually overkill for matcha (most tins are 1-3oz), so you'd likely use one jar for matcha and the other two for different teas or supplies.

Mason jars work fine for loose leaf tea, but these ComSaf jars offer a couple of advantages over standard mason jars. The clip-lock mechanism creates a strong airtight seal without needing to screw on a lid — reviewers specifically praise the well-made hinges and locking mechanism. That makes it easier to open and close frequently when you're reaching for your daily tea. The 34oz size is also a nice sweet spot for loose leaf tea — large enough to hold a decent supply but not so large that your tea sits half-empty with too much air. Just note that some reviewers find the lid quite stiff at first, so it may take a bit of breaking in.

Tea should be kept airtight, away from moisture, light, heat, and strong odors. The ComSaf jars handle the airtight and moisture part really well — the rubber seal and clip fastening keep a tight seal that reviewers say prevents moisture and even pests from getting in. For the best results, store these jars in a cool, dark pantry rather than on a sunny countertop, since the clear glass won't block UV light. One nice bonus: the clear glass lets you see your tea levels at a glance without opening the lid and exposing your tea to air unnecessarily.

The key factors are airtight seal, size, material, and how often you'll access them. The ComSaf jars score well on seal quality — thick glass construction and a rubber gasket that reviewers confirm keeps contents fresh and dry. For size, the 34oz capacity works well for most loose leaf teas and tea bag collections, though it won't fit a massive bulk supply. You get three jars in a set, which is handy if you keep multiple tea varieties. One thing to consider: the opening is on the narrower side, so if you use a large tea scoop or have bigger hands, you might find it a bit tricky to reach in. A long-handled tea spoon solves that easily.

Generally, storing dry tea in the fridge isn't recommended because condensation can form every time you open the container, which degrades the tea. If you do refrigerate tea — say, a delicate green tea or matcha — you need a truly airtight seal. The ComSaf jars have a strong rubber gasket that reviewers confirm keeps moisture out, which is essential for fridge storage. Interestingly, reviewers have discovered these jars also work well for storing fresh fruit in the refrigerator, extending berry freshness for weeks. So while dry tea is usually better in a cool, dark pantry, these jars can handle fridge duty if needed.

When choosing a jar specifically for tea, think about how you'll use it day-to-day. These ComSaf jars have a clip-lock lid that's easy to flip open with one hand once you get the hang of it, which matters when you're making tea every morning. The thick, sturdy glass means they won't feel flimsy on your counter. Reviewers love the look of them — the striped glass design makes them attractive enough for open shelf or countertop display. For tea storage specifically, the 34oz size fits roughly 4-6 ounces of loose leaf tea depending on the leaf size, which is a few weeks' supply for a daily drinker.
