I use contact lens cases. The cheap disposable kind. Bought a couple hundred of them from my eye doctor. They work GREAT! I collect the anthers and lay them in the case, with masking tape on the lid with name of plant. I let them dry overnight in the open case, then close and freeze. The contact lens case is air tight. When using the pollen, I turn the case upside down and tap it a couple times to get some pollen stuck to the lid, then turn it upright, open lid and you can flex the lid around to dab the pollen right from it.
Last year, I did some video of pollenating with these type cases, but never took the time to edit it into a real video.
When the pollen is used, or I won't be using that cultivar again, it is easy to remove the tape, wash out the case and start over with some other pollen.
The cases stack really well in a quart ziplock bag for freezing.
