We have come to love these mylar seed bags. They are a great way to build your own seed bank, the smalls are great for holding a few seed packets and the medium and large are good to hold a small to large garden. A great way to build your seed bank is to use the smaller bags to hold seeds of similar storage length. Just label when you need to replace the seeds in that bag. Put all your small mylar bags in a large one and you have a contained, water tight collection of seeds that are ready for you to use when you need them.
We also use them larger quantities of seeds. Store your dry beans, popcorn, or flour corn in these air tight, food safe bags.
