I have had good luck with Amaryllis pollen wrapped in paper. This works well enough for quick delivery. A few days in the mail doesn't seem to harm the pollen, and the paper keeps it dry.

And one time I received poppy pollen in a plastic film canister. I used some of the pollen last year and the rest is in the freezer for the next time I need it.

Thanks Karl.

I'm thinking that anyway that the pollen doesn't get flying all over the place and getting mixed up if there is more than one kind is a good thing

Using a dark colored tissue paper and putting it in an envelope works pretty well.

Thanks Kristinas
Had a successful mail trade last year which expanded my hybridizing possibilities.
The dark tissue is interesting as it would serve as a good backdrop for the pollen colour.
