Hey Supermoto. Depends how long you are planning on keeping them for. Seeds are good for around 2-3 years just in normal zip-lock bag. If your planning on growing or keeping them for longer, then I would say get a small container and fill it with rice, then put the seeds in a dime bag, and place it with rice, then finally seal it, and put in fridge. Now if your planning on keeping them for a long time, I heard some freezer techniques but cant remember them to well.
Good Luck!
