ONE Size 320 does the work of FIVE Size 60. Works in any kind of humidor to preserve the flavor, aroma, and character of your premium cigars. Use one Size 320 for up to 100 cigars that your humidor, wineador, cooler, or tupperdor is designed to hold.



Preserve your favorite smoke moments with the most versatile Boveda ever! ONE (1) Size 320 = FIVE (5) Size 60. Use in large, medium, or small humidors.   

A Size 320 is for:

  • More condensed power for a wineador or larger humidor, cooler, or tupperdor (Use one (1) Size 320 for every 100 cigars a humidor holds.)
  • Long-lasting maintenance-free cigar care in a small/medium humidor or tupperdor (In a 25-count humidor, the Size 320 can provide cigar protection for up to 1 year.)

Keep a tidy humidor? Slip the Size 320 onto a Boveda Mounting Plate, which affixes to the lid, shelf, or side of a humidor.


Boveda is safe to touch cigars. 

  1. Remove the clear overwrap from the Boveda. (Keep the Size 320 in its outer cardboard box—it provides protection and stability.)* 
  2. Place the Boveda anywhere in your humidor or onto a Boveda Mounting Plate.  
  3. Close the lid. That's it!
  • DO NOT mix different RH (Relative Humidity) levels within the same humidor. 
  • DO NOT use Boveda in the same humidor with other humidification products because they'll counteract each other, and reduce the efficiency of the Boveda.

*If a Size 320 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.


Each Boveda Size 320 is individually overwrapped. 

Unopened, Boveda can last up to 2 years.


5"/12.7 cm x 6.75"/17.145 cm x .81"/2.06 cm


Replace Boveda 2-way humidity packets every three (3) months.


Boveda maintains inside relative humidity (RH) of +/-2% when using the recommended number of packets. Factors that adversely affect the expected results include a drafty humidor and/or extreme dry ambient conditions.


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

    320 Gram Packs - Awesome

    I've used the 320gram 69% packs in my 300 count humidor for quite some time now. Super easy to use, just replace after 6 months or so. Why use anything else?

    Ready to use for the new cigar humidor

    I just purchased a new humidor, seasoning it, and have the Boveda 69% RH Single Size 320 on standby to move in when the seasoning time is complete. I have used Boveda for about a year and appreciate its quality and reliability. I have used the 60-gram individual packs, seasoning kits, and the 320-gram products. The results are there every time.
