Are these ards disposable?

no, they are very durable. Not thick like the old cardboard type, more like a heavy duty playing cards set. You will get lots of use from them, enjoy !

Yes, they can be resharpened; the problem is to find a place that offers that service. Good luck!

I had to toss 2 of them as soon as they arrived because they were dry as a bone. So, Yes, they are disposable

No. You can buy them on Amazon for super cheap though. Each one lasts a month or so.

No -- they are silica crystals, which are not soluble or biodegradable. You'd be asking for a plugged-toilet problem. ...Steve N.

Not at all..when we finished using them I even washed them..they are reusable

Not a problem here. I wouldn't put them through a sanitize cycle, but a plain hot wash/cold rinse/air dry has worked perfectly for us.

Disposable. If you wanted something reusable i would get an ace wrap and dressing separately, then you could reuse the ace wrap and change the bandage and it would work similarly.

I'm not exactly sure. But I've had some last me months of use. Basically once they fill up with too much particulates they kind of clog and it becomes difficult to breath with them. That's when you know to throw them out. If there's a lot of dust on them I knock them against my foot. Just hit the outside a couple times to knock the dust off. It will make them last a little longer. They're really great if used correctly

no, but why do you ask? since they are plastic tubes, that seems wasteful, but maybe you are thinking they would last longer? They come in a big cardboard tube.

No, they are re-usable. They are like the NICU one's that you throw away after one use. But considering the cost, I used them about 5 times max before desposal, I'd just wash them with soapy warm water. They worked fine. Glad our little one graduated from them though. They cost a pretty penny.

I've wondered the same thing. I don't think they are supposed to be reusable, but I can reuse them if I keep them clean.

Probably not. They react to the O2 in whatever environment they are in. If you are keeping them in a mason jar there is a lot of O2 in there, especially if you are constantly opening the jar. Best way to use them is to plan ahead and use them only as needed. I use them when dehydrating vegetables or making jerky. I portion out the vegetables or jerky into vacuum bags, open the vacuum bag containing the Oxy-Sorbs, take out the number required and immediately reseal the bag containing them. I then put a Oxy-Sorb AND a desiccant packet into the vacuum bag with the product and seal it. I keep all the dehydrated products in PLASTIC .50 caliber ammo cans in a freezer, (labeled, dated, etc.) and have found NO deterioration in the products for over 3 years. The Oxy-Sorb is great for long-term storage of products, if used properly.

Totally reusable. I would say heating and using that they probably lasted 3-4 weeks before one would deflate. I would buy 2-3 pairs and just rotate a new one in as one needs to be thrown out

No. They are rewritable. Look at the MTBF numbers. That should give you an idea of how long they should last.

The are disposable, but you can shake them clean and reuse them a few times before they have to be replaced.

Yes, they are only supposed to be used 1 time. They are disposable. You may be able to use them twice but I wouldn't risk it.
