Boveda 62% Two-Way Humidity Control Packs For Storing 1 oz – Size 8 – 10 Pack – Moisture Absorbers for Small Storage Containers – Humidifier Packs – Hydration Packets in Resealable Bag

They seem to be effective. Last year’s crop is in giant jars and are still quite fresh. I would buy them again.

Disappointed in Boveda. Arrived 70% dried out and in a plastic bag that said Stays fresh for 3 years. We expect these to arrive Fresh, not having to rehydrate them for several days before they can be used. No quality or inventory control going on there.

Received an original item and not a repack. So that is good. Havent started using them yet, concerned about the controversy I am hearing about regarding chemical leaching. Going to do more research before use. Be safe all!

The fact that it is reusable for a year is awesome. It keeps my weed fresh as when it was picked.

Nice

After couple week and three packs later, humidity has went from 80 to 69 and still dropping. Pulled the old packs out going to try the put a damp paper towel in with the three dried up ones and see if theyll revive in a sealed sandwich bag.

My son collects and plays Magic the Gathering. He discovered that you can use these packets on the bent / curved foil cards. You just place a couple of packets with them in a sealed container and it removes the curve. As it turns out the cards have too little humidity/moisture which causes them to bend. Using these removes the bend after 3 - 5 days. The images are not perfect before and after shot but you can see how it pulled the bend out.

Wish I would of bought these a long time ago. They work perfectly!

Old item. Already drying out within days. I’ve purchased these before and they last months. This time within days each packet started to harden and dry out. Would not purchase again

You can re-use the used packets. Soak in purified water. Wait for packets to soften, bam. Refurbished ones arent as good as fresh ones but they work.
