Preserve your favorite smoke moments with the most versatile Boveda ever! ONE (1) Size 320 = FIVE (5) Size 60. Use in a large, medium or small wood humidors to precisely manage moisture with Boveda 2-way Humidity Control. The 75% accommodates a high amount of moisture loss, allowing a cigar humidor to maintain proper RH.

75% RH is for:
  • Drafty, leaky or inexpensive wood humidors and glass-topped humidors (In an airtight plastic or acrylic humidor, 75% RH is too high.)
  • Challenging climate of year-round low humidity or high altitude
  • Better burn if cigars burn too quickly
  • Prefer a more-humidified cigar
  • Up to 5 lb of aromatic pipe tobacco
A Single Size 320 is for:
  • More condensed humidity control for a big humidor (Use a Boveda 320 instead of several Size 60 packs.)
  • Long-lasting humidity control in a small wood humidor (In a 25-count humidor, the Size 320 provides cigar protection for up to 1 year!)


Boveda is safe to touch cigars. 

First remove the clear overwrap from the Boveda, then simply place the unwrapped pack in your humidor and close the lid, it’s that easy. Boveda 75% RH automatically restores and maintains humidity in drafty desktop and cabinet humidors. (Use at your discretion if you store cigars in a very dry climate or at high altitudes.)

Don't mix RH (Relative Humidity) levels within the same humidor. And do not use Boveda in the same humidor with other humidification products because they will fight against each other and reduce the efficiency of Boveda. 

Use one (1) Size 320 Boveda for every 100 TOTAL cigars a humidor can hold. Example: For a 250-cigar capacity humidor, use three (3) Size 320 Boveda at once. For smaller humidors, you can also use Size 60 Boveda

Each single Boveda is individually overwrapped. 

Keep the Size 320 in its outer cardboard box—it provides protection and stability. (And attaches to a Boveda Mounting Plate, which lifts your pack up and out of the way.) If this Boveda doesn’t fit in your humidor, you can remove the Size 320 from its outer cardboard box. Just make sure the blue packet doesn’t get pinched or crimped when you close the humidor’s lid.

In a humidor: 2 to 4 months (will last up to a year in a smaller 25-count humidor)
Unopened package: Up to 2 years 

To increase the lifespan of Boveda in a wood humidor, season your new humidor with Boveda for Seasoning packs. 

Do the touch test. Order replacement packs BEFORE Boveda is totally rigid to avoid a lapse in humidity protection in your humidor.
Boveda is still working if you feel: • Hardening at its corners • Soft spots among some hard areas
Boveda is expired if: • The entire pack feels rock solid all the way through. 

It's common that the actual RH of a humidor will stabilize up to 5 points lower than the Boveda RH you use because of humidor quality and ambient dryness. In an airtight environment, all Boveda are accurate to +/- 2% of the RH printed on the pack.

Food-grade salt, purified water and a food-grade thickening agent. 

Size 320: 6.75" x 5" x 0.82" 

Slip the Size 320 onto the Boveda Mounting Plate, which affixes it to the lid of a humidor.

3 Steps to Protect


Place Boveda in your humidor right on top of your cigars or use a Boveda Holder. If your Boveda is wrapped in a clear overwrap, remove the overwrap first before putting Boveda in your humidor. Boveda is FDA compliant food safe.


Boveda will begin working immediately to precisely stabilize the humidity levels in the humidor.


Know with confidence that your collection is protected. Enjoy the perfect smoke, every time.

    Probably me

    I gave this a three star rating because my humidor still refuses to come up to 70 percent humidity. I’m new to this so I’m sure it’s something I’m not doing correctly.

    I recently added a separate humidifier in hopes of getting my humidor up to 70 and that seems to be working.
