Mailing beans via usps?? (if this is against the rules i apologize)

I wanted to send a friend some beans via usps. i was thinking brown bubble wrap mailer (that you usually receive dvds in) with a dvd+case and the beans inside. i wanted to send him 15-20 beans.

is this a good method?

also if so i was wondering how to go about mailing it as im not sure how much postage would be for something like that...id hate to not put enough postage that it never arrives (not putting a return address...and yes ill be using gloves).

so how do i go about getting this package mailed off? going to usps to have them weigh it and put postage on it seems sketch to me but is that the only way of doing it?

I have mailed that way before.
In a cd case, tons of ways bro, its too easy to get em from a to b.


The small bubble wrap mailers. The manila ones (4"x7") Is what I have used to ship them, internationally too.
To get em to canada its 75c and within the US its under the weight limit if its just seeds so one stamp and in a box will do.

I just throw them in some tissue or between thin foam and into a regular envelope. Have a pocket scale? Pricing is as follows:

Weight Not Over Price 1 ounce $0.44 2 ounces $0.64 3 ounces $0.84 3.5 ounces $1.04
