Sealed in sets of 10

Open 10. Keep 90 fresh.

Most brands pack all 100 in one pouch, so every absorber meets air the moment you open it. Ours come in 10 sealed sets, each with an indicator that shows if air got in.

Sealed in sets of 10

Open 10 at a time. Not all 100.

Oxygen absorbers start working the second they touch air. So when a pouch of 100 gets opened, all 100 start wearing out, even if you only need 10 today.

The usual way

One pouch of 100

All 100 exposed the moment you open it. Use 10, and the other 90 are already losing strength.

The Wallaby way

10 sealed sets of 10

Open one set, 10 exposed. The other 90 stay sealed and full strength until you need them.

Indicator in every set

Know if a set got exposed to air

Every sealed set has its own indicator. If a set was accidentally opened or the seal failed, the indicator tells you before you use it. No guessing, and no wasted batch of food.

Good to know

Why doesn’t my bag look vacuum sealed?

Because the air around us is only about one-fifth oxygen. The rest is mostly nitrogen.

An oxygen absorber pulls out the oxygen, which is the part that spoils food. The nitrogen stays in the bag, and it’s harmless. So your bag may tighten a little, but it won’t shrink down like a vacuum bag.

A puffy bag doesn’t mean the absorber failed. It means the oxygen is gone and the nitrogen is left.

Description

Wallaby oxygen absorbers are the companion to your Mylar bags. They remove the oxygen left inside a sealed bag, the main cause of mold, stale taste, bugs and lost nutrients.
Unlike a single pouch of 100, ours are sealed in sets of 10. You open one set, use it, and the rest stay protected until their turn. Pair with low-moisture foods like rice, beans, wheat, oats, flour or freeze-dried meals.

How to use

Pick the right size: 300cc for cup to quart bags, 400cc for 2-quart and gallon, 500cc for 2.5 gallon (use 2).
Fill the bag with dry, low-moisture food.
Open one set of 10 and drop an absorber in. Work fast, and reseal or store the rest of the set right away.
Press out the extra air and heat-seal the bag. No vacuum sealer needed.
Label the bag with the contents and date.

Arrived in EXCELLENT condition.
I was very pleased with these O2 absorbers. Dots were pink and everything was great. Fast shipping, great price! 10 - 10packs of 400cc

Perfect
I was researching the best way to store rice long term. The wallaby oxygen absorbers are top rated, so that was easy. I then read that regular vacuum seal bags are not good for long term storage, so I bought the wallaby mylar bags too. Rice in the bag, absorbers on top, heat seal. Simple. The next morning the bags were pulled tight against the rice. Perfect seal.

Good to have extra absorbers
I use these for my jars that I only open on occasion, but want them to stay fresh. Work well!

Well packaged and clearly labeled
The oxygen absorbers were well packaged, of high quality, and all of them had a light pink oxygen indicator. I like that they were labeled indicating the amount of oxygen they absorb so that If I don't use them all at once, there's no guessing in the future as to their capacity. I will purchase all of my food storage supplys from Wallaby from now on.

FAQ

Questions before you seal?

Call or text a real person, 11am–5pm CST: 213-523-3329

Why doesn’t my bag look vacuum sealed?

Air is only about one-fifth oxygen. The rest is mostly nitrogen. The absorber removes the oxygen, but the nitrogen stays, so the bag tightens a little without shrinking like a vacuum bag. That’s normal, and it means the oxygen is gone.

How many oxygen absorbers do I need per bag?

The rule is 400cc per gallon of food. We suggest 300cc for cup, pint and quart bags, 400cc for 2-quart and 1-gallon bags, and 500cc for 2.5-gallon bags, using two per bag. Using extra is safe.

How do I know if a set was exposed to air?

Every sealed set of 10 has its own indicator. If the set was opened or the seal failed, the indicator will show it. You can also feel a spent absorber: it becomes hard.

How long do absorbers last once opened?

They start working right away, so use them within 10 to 15 minutes. That’s why we seal them in sets of 10: you open only what you need, and the rest stay sealed.

Can I use more than one absorber in a bag?

Yes. They only react to oxygen and don’t harm your food. It’s better to use too many than too few.

Do I need to vacuum seal my Mylar bags?

No. Press out the extra air and heat-seal the bag. The absorber takes care of the oxygen that’s left.

Can I use them in cans and jars?

Yes. They work in #10 cans, mason jars and other airtight containers.

What foods work best?

Dry foods under 10% moisture: rice, beans, wheat, oats, flour, pasta and freeze-dried meals. Skip oily or moist foods like jerky, nuts and brown rice for long-term storage.

Are they reusable? Do they change taste?

No and no. Once active they can’t be reused, and they don’t change taste or texture. They’re food-grade and only remove oxygen.
