Boveda 62% Two-Way Humidity Control Packs For Storing 1 lb – Size 67 – 4 Pack – Moisture Absorbers for Storage Containers – Humidifier Packs – Hydration Packets in Resealable Bag

I grabbed this 4-pack of Boveda 62% Packs to keep a pound of goods fresh in an airtight container, and they’ve been a reliable humidity hack. Each Size 67 pack (2.75" x 5") uses Boveda’s patented 2-way tech—saltwater magic that either releases or absorbs moisture to lock in 62% relative humidity (RH). I’ve been using them in a gallon jar for a few weeks, and they’ve kept everything at that sweet spot—moist but not soggy, vibrant but not moldy. Perfect for long-term storage or reviving stuff that’s gone too dry.The setup’s brain-dead simple: pull a pack from the resealable bag, toss it in your container, and seal it up. No water cups or guesswork—they just work. The 4-pack is sized for up to a pound, and one pack has handled my half-pound stash solo so far, still feeling soft after a month (they’re good for 2-4 months, depending on air exposure). The resealable bag keeps spares fresh, and they’re safe to touch your goods—food-grade materials, no weird leaching.A couple quirks: they’re not rechargeable—once they harden, they’re done, so plan replacements (about every 3 months for me). Also, the 62% RH might not suit everyone—58% could be better if you prefer drier storage. Compared to generic humidity beads I’ve tried, Boveda’s precision and no-maintenance vibe win out, though they cost more upfront.For anyone storing a pound of humidity-sensitive stuff (herbs, cigars, whatever), these are a smart pick—effective, fuss-free, and consistent. I’d rate them 4.5 stars, rounded up to 5 for the tech and reliability. Just match your RH needs and container size!

Grew about 3 pounds of flower(after dried) little over a year ago and had to leave it behind when I left to work out of state with these packets in the jars. Now I'm back and finally able to break into the stash again, it's as fresh and sticky as the day I jarred it and has grew in potency with it's maturity! Absolutely a necessary if you've got alot of flower or have to store any long term, absolute quality product with plenty life left after a year of use.

Excellent product
