Boveda Metal Holders
About Metal Boveda Holders
You can also use the magnetic kit to stick several metal holders together if you like the look of the metal but need more Boveda packet-holding capacity. Or, orient the packet holders vertically and do a side-by-side look.
For travel humidors, simply cut out the foam usually present in the lid just a little smaller than the size of the metal holder so the holder fits snugly in place. You would not use either the velcro or magnetic mounting kit in this case.
The metal holder is an optional accessory and is not required for using Boveda packets, it just provides an elegant way to keep the packs out of the way.
Note: Do not mix Boveda RH levels within the same humidor, and do not use Boveda in the same humidor with other humidification products. They will fight against each other and reduce the efficiency of the Boveda.
