I use the veggie caps, of which I have more than one size.
They were obtained through a bulk herbal supply company some 10 years ago, so I don't know exactly what they are made of, or who sold them.  (They actually sent me free samples of 200-500 each)

Notably, my capped specimens are then stored in fiction-fit plastic container.  Thus solving any vermin and air exchange (humidity) problems.
